Just remove the 2 lines of code you add to the file. I use navigation everyday and it would fail evey 10 min's without the 3g fix. Not sure what your issue is but this works for me.
[Nexus One General] clandest:
whats required to do this? Just a terminal app on the market?
[Nexus One General] icon57:
thanks shep...the issue i had was when i first applied this fix, and rebooted 2x

i then completely lost google navigation....it would launch, but never get a fix on my location...the screen would just stay white...dont understand myself why this would have happened....to correct it the only way i could think of at the time was to do a nand restore....this corrected the issue...for navigation...however...i still dont stay locked on 3g, and it will switch right to edge, as opposed to 2g...

i still have the fix on my phone...but i might want to switch back ...im just not seeing any difference at all..
[Nexus One General] Mikey:
I wonder if the guys who bought their phones from Google called T-Mobile to update their imei number???

Also need to switch your G1 data plan to the Android Plan. *Same price*
[Nexus One General] clandest:
I didn't.. Whats that do? I got a fresh plan with tmobile when I got the nexus. I came from att
[Nexus One General] nyzrox:
Is the UK affected by this?
[Nexus One General] icon57:
if you aimed that comment at me..the answer is yeah...did that
[Nexus One General] jchap2k:
Yes I had the same thing happen to me. My battery was getting Nuked :P

I am going to undo this change with all my current apps and see how my battery life is after that.
[Nexus One General] fnordelus:
You will not not be disappointed when you get one, I've been a die hard WM user, and I'v also owned android (G1, Cliq), plam pre, and iPhone, but despite some complaints and poor reviews (engadget), this phone is ABSOLUTELY AMAZING.
[Nexus One General] Beast84:
Is that required for something? I never called to tell them anything. Everything seems to have just transfered over just fine
[Nexus One General] Ssantos6981:
What am I doing wrong? Which terminal emulator are you guys using? I am using the one built into SUFBS and I cannot even get past the mount -o... etc.

I cannot cp, or vi, or edit. Only command that seems to work is mv.
[Nexus One General] Mi|enko:
I pulled the build.prop and edited it with notepad, then repushed it.
[Nexus One General] Ssantos6981:
I don't understand. I've always been able (G1) to cp in terminal and the adb. I have no access to cp. it keeps saying I have no such tool. I am having trouble trying pushing, pulling, copying, etc.

Can someone list off the ADB commands and the terminal commands to copy, and pull/push?

I also cannot use regular adb commands either, they have to be adb-windows, is that normal for the N1?
[Nexus One General] uansari1:
So I've been following this issue on Google's support website, and one of the rooted users over there is almost positive it's a software issue with 2.1. He actually flashed a port of 2.0.1. Although he got lots of FC's, obviously as 2.0.1 isn't made for the N1, he was getting excellent 3G connectivity, and constant speeds over 1500kbps!

Here's the link so you can read for yourself. The user's name is GNove.

[Nexus One General] GNOve:
Hey guys.

Take a look at the google support thread. I tested 1.6 and my connectivity skyrocketed. I dont know how accurate the tests are but I can tell you websites were opening quicker then my droids and the overall browsing experience was awesome.

Is there anyway to port 2.0.1/1.6 driver over to 2.1?
[Nexus One General] BrotherG:
Great Job Gnove. This is probably why 2.1 hasn't been released for any other handsets. I unfortunately don't have a rooted device. Have any of you folks with 2.1 seen any similar issues on T-Mobile?
[Nexus One General] shep211:
If there is a way this is the right place. We need to ask cyanogen, enomther or modaco to see if they can change the drivers or whatever files need to be changed. They may know about this already. They are waiting for the source code for 2.1 to be released to cook new roms.
[Nexus One General] bk420:
What ROM are you using??? Can I just download any AOSP rom that is 1.6/2.0 and run it???

Thanks for the details ahead.
[Nexus One General] neva dinova:
fixed by tmobile?

i dont know if this is the right thread to post this but has anyone noticed a big jump in 3g speeds today? I live in austin and my speeds have for some reason never broke 200kbps but today i noticed that pages were loading faster so i tested with the speedtest.net app and my download was 766kbps and 375kbps for upload
[Nexus One General] Beast84:
Tried this with the 1 10 combination... I don't notice a difference. I have been going back & forth from 3G to Edge just sitting on my couch. I had no issues with my G1 or MT3G. Anyone have any better success with any other combinations?
[Nexus One General] fosormic:
Man. Just tried... numbers between 850 and 1300! Upload around 400.

Didn't notice because kept Wi-Fi on all the time. I'm in Houston.

I'm very glad I dumped AT&T for T-Mo a couple of months ago

:cool:
[Nexus One General] dchadwick:
I read your post and did another test myself today and I noticed my speed had doubled as well.:D
[Nexus One General] mhaedo:
Gotta love T-Mobile Philadelphia :)
[Nexus One General] dchadwick:
OK, I am no where near that fast but it would be nice to see some day. ;)
[Nexus One General] Know-Fear:
I seem to have fixed my 3g issue like this:

Settings/Wireless & Networks

Mobile Networks

Access Point Names

Select T-Mobile US

Scroll down to Authentication type and select 'none'

Exit back out to the Mobile Networks screen and select the Network Operators

Select either TMO or Auto.

Once you go back to the homescreen you should be on 3g. It has worked for me and has been on 3g overnight without switching back to Edge.
[Nexus One General] HydrantHunter:
In Olympia, WA, US setting AuthType to none results in no connectivity for me. AuthType was defaulted to 'not set' on my N1 - I'm wondering how many other settings are 'not set' until switches are flipped like Airplane Mode, etc...and if any of that might actually be helpful (or even necessary when moving between coverage areas...e.g. state to state).

Last night I switched to Airplane Mode for a couple hours, then back and I've had much better 3G reliability...though not any noticeable increase in speed.

One thing I noticed before the Airplane Mode switch was that going into Maps would cause my connection to 'freeze' with only the upload arrow lit. Tiles wouldn't download and quitting Maps was the only way to get back any kind of connection. Maps hasn't had this problem since I switched Airplane Mode on and off.

I hope this is useful to someone. Rebooting, BTW, never helped any of this for me.

** Update 1/24/10 **

The 3G freezing in 'upload only' happened to me again last night in the Market app while updating my apps. I had to exit Market and start GTalk (which had to log in) - that resolved the issue for the time being.

I wouldn't be surprised if T-Mobile is having some issues with their network since the 3G rollout; but the problems I'm having and the anecdotal data I'm seeing point back to the phone and Android 2.x. When compared with my G1 I have noted the following:

- G1 on 2.x (especially 2.1) has lower phone signal strength (by 1 to 2 bars) and semi-regular 3G connectivity issues (although not as severe as the N1).

- The same G1 on 1.x has none of these issues in the (exact) same location or any variety of locations.

If these issues are software related I have little doubt the problems will be fixed eventually, but Google's dog-fooding process probably needs some serious rethinking.
[Nexus One General] kep0ne:
A combination of both setting the auth type and turning on airplane mode fixed my 3g issue for now...seeing 1300 down and 400 up
[Nexus One General] jaypr9:
Does this fix still work? I mean even after the update? The "update" did nothing for me so I've decided to try other ways to fix and was just wondering if this was working out ok for the people who had done it.

I havent yet rooted my phone but if this is working I sure will give it a try.
[Nexus One General] bmj1086:
I think some of you are just too set on having an issue that you think you have one. When I'm driving around Dallas with my wife [who has my old MyTouch] we have the same signal strength. I don't see any issues with 3G. My cousin has a Nexus One also. No 3G signal issues. Google stated that they have fixed anything that would be an issue.
[Nexus One General] ssj4vegita2002:
Unfortunately there is still a legitimate issue. At work on both the g1 and n1 I get full bars of 3G at my desk. If I go into the bathroom I get 3 bars of edge, understandable due to low building signal penetration. The problem comes when I head back to my desk. I'll get full edge. It refuses to try and get back on 3g, even though I can get full bars of it. It will only reconnect to the 3g signal if I use my anycut shortcut to phone info and switch from wcdma preferred to wcdma only, and then back.
[Nexus One General] SiNJiN76:
Ha...still having issues. 2 nexus ones side by side. Full bars. one goes to Edge...the other stays on 3G. Then vice versa...then both on EDGE...then a few minutes later...3G.
[Nexus One General] jaypr9:
Sorry but there is most definitely still an issue. Not sure why I would want this "issue" of not having 3G. Even Google seems to know there still something going on from their forums. Myself when my phone is sitting on my desk it shows 3G, soon as I pick it up it goes to E. I'm right in the middle of 3G coverage according to the maps.

I mean even just to work which is along I95 towards NYC which is all covered in 3G my phone flips back and forth. Just check the forums and I'm sure you'll see what did with the update did not fix it completely.
[Nexus One General] j2eubank:
I have this exact scenario at work at my desk.
[Nexus One General] TailsNeon556:
ive resorted to cycling airplane mode.. usually kicks it back to 3G.. this problem along with the wacky DL/UL speeds is quite annoying.. this update didnt fix squat
[Nexus One General] bmj1086:
It doesn't matter if you're in a 3G coverage area according to the map. Just because you have 3G according to the map doesn't mean you should always have 3G in that location. It means you 3G is available in that area. If your signal strength isn't strong enough then you drop to edge. Have you guys been on T-Mobile for a while or just joining? It's been like this forever. Their signal strength simply isn't as strong as it should be. Nothing has change for me from G1 to MyTouch to N1. T-Mobile's 3G coverage is just that.

Also I'd like to mention when I updated the Radio It fixed the original issue. Are all of you on the newest radio?
[Nexus One General] dnanj:
I have to agree with dumbestcrayon! I live here in Fort Worth, and according to the Tmobile's coverage map, I have great 3G coverage, which I do, but all that changes once I step into the house. It doesn't matter what phone I'm using. My nexus behaves the same as the other phones I've used(g1, mytouch, cliq, N900) and would switch from 3G to Edge and back depending on which part of the house I'm at.
[Nexus One General] jaypr9:
I am on the newest radio as I've applied the update when it was released. Still seems strange that people have noticed a lower signal with the N1 as compared to other phone side by side.

Also if the the 3G and voice signal meters have no relation why is it as my my voice meters starts to drop is when I switch to E. I could have 3G while the phone is sitting on my desk with 2-3 bars of voice. Soon as I pick it up the voice bars start to drop to 0 then my 3g switches to E. I always thought they werent completely different from one another.

Ah well I guess we are all the mercy of Google. Sorry Crayon I understand you feel as there's nothing wrong with the radio but there's a lot of us who see somethings just not right.
[Nexus One General] SimonNWalker:
I'm still having issues and will doing more testing over the next few days.

When I upgraded to the new radio I would occassionally loose my data connection all together. I woke up the first morning and my phone had a full voice connection and no data icon at all.. I turned to 2G only and then back to 3G and it was fine again. This happened a couple of times.

Im now back at the original radio and still having some issues.

Im going to start fresh with my original Radio and Nandroid backup of original release and work from there.

If that seems ok for a couple of days, Ill flash the new radio and see what happens.

Let's hope we can get this officially resolved.
[Nexus One General] ssj4vegita2002:
I've been with T-Mobile for about 6 years. In the same area. After working where I do for the past 4 years, and using the G1 since launch, there is a definite difference between it and the N1 when it comes to switching from 3G to EDGE and back. The G1 NEVER had a problem re-acquiring 3G when I came back to my desk. The Nexus One, if I let it sit the rest of the day, will NEVER connect back to 3G, even though I can get full bars. A quick cycle of the WCDMA settings and it will. None of this makes me hate the phone or want to get rid of it. it's just an inconvenience.

And yes, I'm on the new radio update, it didn't seem to help at all. Hell, I'm even getting those new boosted speeds t-mobile was talking about. I'm getting about 3mbps down and 1.5mpbs up. The phone just refuses to find 3G again after it has switched down to EDGE, for whatever reason.
[Nexus One General] dnanj:
I can't say that this is a problem with the nexus one, because whenever I'm at home, I have experienced the same signal switching issue with the G1, mytouch, cliq and a even with a non-htc phone(Nokia N900). When I'm at school, I get 3-4 bars of 3G and don't experience this issue. I can move around practically anywhere and the phone stays on 3G. That being the case, I honestly feel that this is more of a problem with Tmobile than it is the phone.

Edit:

I am using the stock/original radio that my Nexus came with and keeping in mind that I never had great @home 3G experience on any of the phones I mentioned above, I find that whenever I step out of the house, my Nexus 1 immediately switches from E to 3G if it wasn't on 3G to begin with.
[Nexus One General] TailsNeon556:
i would like to flash the old radio as well..as it was better than this new one by far.. how do i go about doing this? and do i have to root it? considering i flashed the new update without root.. i have the old radio (from enom's thread)but im always afraid of radio flashes from the nightmares we had with the G1 a while back and i dont want a $530usd brick
[Nexus One General] bmj1086:
That's crazy. Some times mine is a little slow getting back to 3G but so was my G1 and MT3G. It's nothing more than a few seconds or more usually. I live in dallas and I see no Speed boost at all.. I'm still getting like 600/400 on full 3G signal....Pathetic. My cousin has an N1 on Tmobile also and we get the same results.
[Nexus One General] ssj4vegita2002:
Yea, it's definitely strange. it never happened with my G1. And the speed boost is in the NYC suburbs area, just an FYI.
[Nexus One General] bmj1086:
Ah. Did you guys get HSPA+ or something? They upgraded to 7.2 and I saw no change...The download and upload speeds are so bad it irritates me.
[Nexus One General] guyen01:
Yeah i was wondering about that too, I keep on doing speed test and its about the same. I get maybe 120KB a sec with 5 bars, but its normally 60KB a sec. Anyone do a test with a different phone to see if they get 300-700KB a sec? Maybe its just the nexus one.
[Nexus One General] guyen01:
As your resident cheerleader for T-Mobile, I feel compelled to update you about any news concerning the carrier’s 3G upgrades to HSPA 7.2 and HSPA+.

T-Mobile recently completed their upgrade to HSPA 7.2, but many customers did not receive the dramatic speed boost they were expecting. We were wondering why T-Mobile was not doing more to promote the faster 3G standard and found out it was because the carrier had not finished upgrading the backhaul to their towers.

After a short breather, it looks like T-Mobile is ready to push on enhancing their nationwide network to make it the fastest in 2010.

GigaOm posted several new network details in an interview with T-Mobile’s Dave Mayo, VP of engineering.

* T-Mobile has currently deployed fiber to about 7 percent of its towers (with 20 Mbps of capacity on those fiber strands).

* The operator will turn on fiber to about 25 percent of its towers within the next few weeks.

* The first markets to receive HSPA+ (21 Mbps) will be along the California coast and “major cities from Washington, D.C. to Boston”.

T-Mobile chose to go with HSPA+ because it is easily deployed over their new 3G network and it will allow them to offer the fastest nationwide 3G in 2010. Other carries are focusing on new technology like LTE and WiMax, but T-Mobile will complete their HSPA+ upgrade by mid 2010.

According to some hands on reports, T-Mobile’s HSPA+ network might be faster than Sprint’s new 4G WiMax. It will be interesting to see how the carrier will market the network and if they will still call it 3G or 3.5G.

T-Mobile is still sitting in 4th place among the U.S. carriers, but I think their aggressive support of Android (first carrier with the Nexus One), cheapest smartphone plans, and the fastest network should help them close the gap in 2010.
[Nexus One General] ndboost:
So tell me... does the Nexus One support HSDPA+ I know i get the HSDPA Icon at times (The H Icon instead of 3G).. and from everything i've read HSDPA is much faster than 3G..
[Nexus One General] miketaylor00:
Here you go.

http://lmgtfy.com/?q=does+the+Nexus+One+support+HSDPA
[Nexus One General] ndboost:
Yes i already googled it, and for anyone else that is curious and is finding themselves coming to THIS forum for the same question..

Nexus One supports HSDPA (7.2Mbps) but not HSPA+ (some know it as 3.5G)
[Nexus One General] lessthanjoey:
Does anybody have a link to an img of the original radio (32.19.00.16U_4.02.02.14)?

I tried searching but no dice. I'd like to flash back to it without making everything stock again.
[Nexus One General] SiNJiN76:
check enom's rom thread. He's got a link there.
[Nexus One General] SimonNWalker:
Yes, You will have to root your phone in order to flash the radio.

Once rooted, you need to download the old radio update file from AndroidSPIN and then flash it on your phone.

You perform the downgrade of the radio just like you would flash a new ROM on your phone, using Amon_RA's recovery tools.
[Nexus One General] SimonNWalker:
I've been performing tests for the last 24 hours and currently my issues has gone.

I'm not exactly sure why but the issue has gone yet, but I have started documenting my testing.
[Nexus One General] ssj4vegita2002:
A very telling video - http://www.engadget.com/2010/02/11/nexus-one-3g-problems-persist-after-update-is-it-a-design-pro/

I'll have to do my own little tests and see if mine does the same. Let's hope it isn't a design flaw.
[Nexus One General] mautai916:
mines does the SAME THING

I highly suspect to be a hardware issue due to the fact that it literally loses all signal and drops from 3G to EDGE. Seems more like a design flaw where it might be poorly grounded at one point?

I just highly DOUBT that this will be fixed with a OTA update when it seems more like hardware is at fault?
[Nexus One General] ssj4vegita2002:
Yea, just did the same tests and got the same results. This is kind of huge if it's a design flaw.
[Nexus One General] aob:
What's the app that he's using in the Video?
[Nexus One General] ssj4vegita2002:
That's the Phone Info shortcut. I have it set through AnyCut.
[Nexus One General] Mikey:
I have to say, if i hold my phone like the guy in the clip, i dont loose signal drop.

I have to completely cover the bottom of the phone with both my hands to loose 3G.

I guess im a lucky one??
[Nexus One General] uansari1:
I think this "issue" has more to do with HTC's antenna placement AND T-mobile's level of 3G saturation. In some areas, there is a lot of overlap of 3G, as compared to other places. Mikey, I see you're from Chicago... I imagine Chicago has great 3G saturation, versus Toledo, OH, where I am... Then again, it will probably vary within any city as well... I wouldn't be surprised if this is an issue that won't be as prevalent on a broader network like VZW when they get the N1 in a couple months.
[Nexus One General] Mikey:
We might have stronger 3g butt you guys have better college football team lol
[Nexus One General] Drethis:
Crap, I'm getting the same issue like the Engadget Article. Does anyone know if Google/HTC has taken note of this or made any comments?

I'm in Canada so this will be a huge problem for me if I have to ship it back to them. :(
[Nexus One General] genibus:
It has little to do w/the 3G saturation of TMO. I'm sure you are very aware that the other android devices (G1, MyTouch, CLIQ, etc) do not experience this issue.

And with the latest leaked radio image I've noticed significant improvement, matching & besting that of the CLIQ. It wont let me post links on my account yet but up one level in the forums you'll see my analysis on this. Topic# 632282

[Nexus One General] telhunter:
Guys I did the same test and while I did drop to Edge with additional testing I found that in the WCDMA only mode my Nexus only lost a few dBm worth of signal but did not lose 3G connectivity. In my opinion this is a software problem, they can fix this.

P.S. I have nearly no 3G issues since leaving my Nexus in WCDMA only mode in the New York City area.
[Nexus One General] simms22:
check these out, nyc baby!(in queens. i max out around 2000 in brooklyn)
[Nexus One General] uansari1:
I was in Chicago over the weekend and I can verify what Mikey said. I couldn't get a drop in 3G by holding my phone around the bottom at all. Maybe got a one bar drop if I held it in a way no normal person would. I strongly suspect this is more a T-mobile fault than HTC.

LMAO... I actually spent two years of undergrad at OSU. I'd rather have the stronger 3G. ;)

I understand what you're saying, and I do believe that the placement of the antenna in the N1 (which is different than the placement in the G1, which I had before) has an impact...and maybe software COULD be tweaked more as evidenced by people using the newest unreleased radio. But that doesn't account for the experience that people are having in some larger cities where T-mobile has a strong network presence. Like I alluded to above, I was just in Chicago and had ZERO loss of 3G. I was pretty much at full bars all the time, and maybe got it to drop to 3 bars by wrapping both hands around the bottom of my phone.

So to summarize, I think HTC's engineering of the antenna is to blame somewhat, since we didn't see similar issues with the G1 or MT3G... but if T-mobile had higher network saturation in the areas we're in, I'd bet we wouldn't experience these issues at all (again, like when I was just in Chicago).

The reality is that as phones get slimmer, antenna placement will probably not be ideal as compared to thicker phones... but the only people that will see problems is poor shlubs like us who live in cities where T-mobile hasn't invested as heavily in the infrastructure.
