I was looking at the Nexus One teardown here. http://www.ifixit.com/Teardown/Nexus-One/1654/2

Interesting to note that the RTR6285 RF transceiver does indeed support Band 5 UMTS, which I think is AT&T, according to a cached press release here. http://74.125.153.132/search?q=cach...l+RTR6285+umts+bands&cd=1&hl=en&ct=clnk&gl=us

Note it says...

North American triple-band UMTS (bands 2, 4, 5)

Japanese triple-band UMTS (bands 1, 6, 9)

European, Chinese and rest-of-world triple-band UMTS (bands 1, 3, 8)

Also... the power amplifier SKY77336, according to this document... http://docs.google.com/viewer?url=http://www.skyworksinc.com/uploads/documents/200780E.pdf

Does support the GSM850 band. Isn't that AT&T?

So what is really preventing the Nexus One from running on AT&T? Did they just not "bother" to certify it with the FCC because T-Mobile is their launch partner?

This could mean then the radio software, or some other configuration option in the firmware simply has AT&T 3G disabled.

I'll let you guys debate this, but I can't see any hardware reason why this phone couldn't work on AT&T 3G, with proper software/hacking of course.

-James
[Nexus One General] GuestK0050:
Actually the real question is, why didn't they certify with the FCC for AT&T 3G? My only idea is that T-Mobile was the launch partner, but the hardware can do AT&T 3G technically, it's just not certified and enabled.

No reason they couldn't certify and enable it later.

And I have to say, I would have no trouble going to T-Mobile, but in Salt Lake City, AT&T coverage is far superior and so are the 3G speed tests. There are many locations my T-Mobile friends can't get make calls to save their life. I hear T-Mobile is much better in other cities.

-James
[Nexus One General] jimbo831:
Doesn't AT&T use both 850 and 1900 for 3G? Does this phone have 1900?
[Nexus One General] GuestK0050:
Believe the transceiver and amplifier support both.

I want to get people digging around on this.

-James
[Nexus One General] deprecate:
Very interesting stuff.

I bet a community could get a pot together and have a prize for whomever can get the n1 working on att first, assuming it actually will work :)

Thanks for digging up this info, I was actually in the process of starting to research this myself for when I grew tired of living on edge.
[Nexus One General] YorikR32:
You've already answered your own question here, GSM is not UMTS.

I'm in the smae boat btw, Telstra in Aus use 850UMTS and I know how painful it can be to have 2G access in most places.
[Nexus One General] GuestK0050:
Well technically UMTS is a GSM standard, could be the same thing. Same frequencies certainly.
[Nexus One General] GuestK0050:
I was just checking the brochure for the http://www.rfmw.com/data/BRO254-08B.pdf

No where does it make mention of UMTS, like say... T-Mobile's AWS... but it does specifically have the correct frequencies listed for both T-Mobile AWS and AT&T 3G.

I'm going to make the assumption that this indicates it works with UMTS is both bands since it doesn't mention UMTS specifically at all, yet it does work on T-Mobile AWS.
[Nexus One General] wick12345:
James I love you man! tell me there's a way to "jailbreak" this thing.... what kind of people do we need? someone has to be willing to help with this. Oh why oh why am i only a MBA.... I need a tech degree of some kind!

I don't think it has to do with the FCC. Though we are all in love with the nexus one... remember that google and apple are nearly HALF of the same executive board. They don't want to compete with the golden goose that keeps thier stock portfolio's up that much.

We just need to find out how to activate/change which airwaves this thing is listening too and THEN we will have the first truely unlocked machine!
[Nexus One General] quaa:
subscribing to this thread for an outcome.
[Nexus One General] wick12345:
I've been doing more reading and it seems this isn't the first phone with hardware disabled. I haven't found anything yet on if anyone has made the change yet :+\
[Nexus One General] ~~Tito~~:
Here we go, the Blackstone all over again :p.
[Nexus One General] Matterhorn:
Well, maybe. The Blackstone has a hardware limitation for the US 3G frequencies. There have been phones in the past that had software limitations that were overcome with a hack. So if the Nexus has the hardware capabilities to do ATT 3G frequencies there is a good chance that someone will figure out how to unlock it.
[Nexus One General] Funk2641:
uh...wow. Yeah, I'll be watching this thread. :p
[Nexus One General] wick12345:
Which phones? Do you have any links we can read so we can start looking for similar solutions?
[Nexus One General] wick12345:
I found this link to the Diamond on XDA which they supposedly change to 3g at&t but I have read the whole thing it's long.

I'm still looking for answers! I'm just not smart enough to "create" the answer. I have hope that a future rom will help us but not for a while. For now I'll keep researching.

P.S. my phone comes tommorrow!!!!!!!!11 I'm so excited!!!!!!!!!!!111111
[Nexus One General] coolbho3000:
The radio chip supports all the UMTS bands it but unfortunately the UMTS power amplifiers (eg. http://www.skyworksinc.com/Product.aspx?ProductID=597) are NOT in the chip. :( Like the G1 it probably only has amplifiers for 900/1700/2100.

The quadband power amplifier only supports GPRS/EDGE: http://www.skyworksinc.com/Product.aspx?ProductID=437

Looking at the chip diagram here (http://s2.guide-images.ifixit.com/igi/ZhrRALhPFhWyLGKC.large) the two chips next to the SKY77191 look awfully like power amplifiers as well.. if so, conveniently for 900/2100 :(

[Nexus One General] coolbho3000:
Don't get me wrong, I wish this worked on AT&T (points at logo). Guess I'm EDGE-only until my contract expires. ;)

Just wish all carriers would have stuck to one standard :(
[Nexus One General] atolar:
whoever helps figure this out will definitely be getting some donations from me!! i have att and no purpose of buying a N1 without 3g...
[Nexus One General] JamieD81:
i live up in canada and went into rogers yesterday asking questions and he said it WILL work on rogers network as one of their 4 bands seems to be 900 which is on this phone.

i asked him over and over to make sure and he said it will. can anyone confirm this?
[Nexus One General] parrot5:
The GSM radio in the Nexus One is quad-band, so it will work on Rogers in 2G mode. The phone uses AWS as its 3G band - 1700 - which Rogers has bought spectrum for, but hasn't implemented anything out of it. So, no 3G for you (or me).
[Nexus One General] JamieD81:
ahh well that helps :P thanks, ill waiit then, g1 will be fine i guesssss. thanks for the quick reply!
[Nexus One General] socalphil:
Okay here is your answer.

The phone has 3 3G power amplifiers. The Skyworks one (77191)for Band IV and 2 Avago PA's for Band 1 and 8(A5008,A5001). So no it definitely does not do ATT 3G. Band 1 and Band 8 are Europe and Band4 is TMO(US).

It also has GSM/EDGE quad band (850,900,1800,1900)

There may be a later version with Bands 2 and 5 for Canada and ATT. It may be what ATT announced yesterday. They will have 5 Android models in the near future. Some from HTC. (Hint,Hint)

Don't ask me how I know this, just trust me.
[Nexus One General] coolbho3000:
My suspicions, confirmed. :(
[Nexus One General] Kermee:
Yeah. No power amps on Bands 2 & 5 == No workie workie on AT&T 3G.

Cheers,

Kermee
[Nexus One General] hurrycaine3000:
big time bummer, I ordered mine yesterday in hopes of finding a solution. I would just switch to t mobile but they have no 3g in my area any way, according to their coverage map. oh well, i guess it's just 2g, and wifi for me at the moment. not sure I'll be able to handle the slow down.
[Nexus One General] Empire101:
Directly from the N1 site.

"The Nexus One device is unlocked and will recognize SIM cards from

ANY

mobile service provider using the GSM standard. The Nexus One's antenna supports four GSM radio frequencies (850/900/1800/1900) and three 3G/UMTS Bands - 1/4/8 (2100/AWS/900). These cover most major GSM mobile providers worldwide, including T-Mobile US, but

not the 850 MHz 3G band used by AT&T.

The Nexus One phone will, however, deliver 2G/EDGE speeds on these networks, and of course supports WiFi as well. For questions about the bands supported by your mobile service provider, please contact your provider directly. The currently available Nexus One is a GSM device and is not compatible with CDMA networks such as Verizon and Sprint. We are working hard to provide Nexus One phones optimized for the Verizon network"

Guess us ATT guys have to wait a little. Unless someone figures this thing out.:o
[Nexus One General] leo_bsb:
So, is there any chance for unlock the 850mhz 3g on the original N1?

[Nexus One General] cboy007:
Hello smart members of XDA. When you get a new device the manufacturer often has something that says "Fully charge before use". I've seen Google has one of these instruction cards and that's number 1 on it. I've done some research, and for every article saying the first charge on Li-on is the same as the 5th charge and thus just charge it regularly, there's an article saying charge it originally for 10 hours.

So, smart members. What is your take? Should I charge my Nexus before using it for 10 hours? Can I use the phone while it's charging for the first 10 hours? Can I just put the battery in and use it and not worry about special charging the first time?

Thanks.

(http://www.batteryuniversity.com/partone-21.htm has a good chart, but neglects this area).
[Nexus One General] rumpleforeskin:
Li-on batteries

general rule is charge it as often as you can and when your home/office keep ya phone in a dock if you have one so it always charges.

Li-on batteries degrade more the more often they are reduced to minimum charge, so for best battery life charge as much as possible.

As for the 10 hour initial charge... who knows!!! i could not think of a technical reason why you should as once the battery is charged the phones internal regulator will not allow you to "overcharge" the device. you can always play with the device when its charging without any adverse effects (except it may take longer to charge if your watching films for example)
[Nexus One General] MarcusMaximus04@gmail.com:
From wikipedia:

Stage 1: Apply charging current limit until the voltage limit per cell is reached.[43]

Stage 2: Apply maximum voltage per cell limit until the current declines below 3% of rated charge current.[43]

Stage 3: Periodically apply a top-off charge about once per 500 hours.[43]

The charge time is about three to five hours, depending upon the charger used. Generally, cell phone batteries can be charged at 1C and laptop-types at 0.8C, where C is the current that would discharge the battery in one hour. Charging is usually stopped when the current goes below 0.03C but it can be left indefinitely depending on desired charging time. Some fast chargers skip stage 2 and claim the battery is ready at 70% charge.[43] Laptop battery chargers sometimes gamble, and try to charge up to 4.35v then disconnect battery. This helps to compensate internal resistance and charge up to 100% in short time.

Top-off charging is recommended to be initiated when voltage goes below 4.05 V/cell.[43]

Lithium-ion[which?] cells are charged with 4.2 ± 0.05 V/cell,except for military long-life cells where 3.92 V is used to extend battery life. Most protection circuits cut off if either 4.3 V or 90 °C is reached. If the voltage drops below 2.50 V per cell, the battery protection circuit may also render it unchargeable with regular charging equipment. Most battery protection circuits stop at 2.7–3.0 V per cell.[43]

For safety reasons it is recommended to stay within the manufacturer's stated voltage and current ratings during both charge and discharge cycles.

I'm on t-mobile and really didn't want to give up my G1 until another Android phone was available with a hardware keyboard. However, I did just purchase the Nexus One (no plan... $80/month data was ridiculous) and was wondering if anyone has had any luck finding the CooTek TouchPal virtual keyboard?

I used to use it on my last (and only) WMo device and liked it. I know they released a beta in the android marketplace but stopped offering it because it was OEM software on the T-Mobile pulse and wasn't going to be re-released in the marketplace until after the launch of that phone.

Was hoping someone had an older copy that might be compatible w the N1.
[Nexus One Themes and Apps] mlevin:
I have 1.1.0. Not sure if that will work on the N1, but you're welcome to try it. PM me and I can send you a link.

Hi everybody!

tonight i tried my hd2 togheter with a iphone 3gs and i noticed a little latency of "touch gesture". scrooling the screen with finger show a little lag between finger position or movement and scrolling action, this doesn't appen with iphone where the screen is always "locked" to the finger giving a different feeling... did you noticed it?

Hi there,

does anybody know how to change the batteri indicator to show batteri usage in 1% at the time. As is it right now it only shows 10 %

have search the forum and looked 20 pages down, havent found anything
[Touch Diamond2, Pure General] Bruce Inman:
You can use Batti 2.4 which puts the bar across the top of your screen and is completely configurable.
[Touch Diamond2, Pure General] CerB:
i know the program :-D but want the batteri indicator to show 1% at the time when i press on the top of the screen
[Touch Diamond2, Pure General] arrow224:
I use this one. It shows it like so: 99, 98, 97, 96 etc until 1

Edit: this is for WM6.1, the standard ROM that comes with the Topaz.

I checked out the android wifi tether google code page and they seem to have an experimental version for the Nexus One. I installed it and have no issues with the installation, but you need to patch the kernel to enable netfilter (obviously).

The problem I am having is we all have "user" builds of the kernel so we can't patch it. We need a userdebug or eng build. Is there any way to change yet? There is a tutorial on how to patch the kernel on their wiki but it wont work unless you have a userdebug or eng build.

Did I miss a new kernel thread or something?

hi

i have ultimate 8105.

the softwares installed use 3g connection automatically to update or work which consume my balance credite which is still expensive in my country.

e.g (yesterday my balance was22 l.e and after some time it reached 0.58 l.e)

so

how can i control or prevent using 3g net without affecting mms and video call function(3g controlled functions).

Can the creative Zii egg or any other android media player run sense ui (I'm assuming sense ui is just another program)
[Android Software Development] psychoace:
It's impossible. It's not a program it's a complete OS. It's a Hero rom that works on Hero devices or similar. The hardware change in the Zii egg will not allow for it to work without tons and tons of work which i don't think anyone will spend the time on.
[Android Software Development] the_fish:
well that is wrong actually. how do you think we got the hero roms on our G1/MT3G's? it's not hard actually as i assume the zii egg supports cupcake, and hero is no specific rom it's just a little modified cupcake :) shouldn't be hard to get it working on the zii egg if its bootloader will be unlocked and the kernel is opensource ;)
[Android Software Development] psychoace:
both are htc phones with almost exact hardware that is how they got it on the g1 and mt3g. The drivers were almost exactly the same so it worked with the egg it's very different

I ordered my Nexus One without a charger and was wondering if I could just use my iPhone USB charger with the supplied USB lead?

I'm guessing that's all the charger is right? Just a charger with a USB port or a miniUSB charger?
[Nexus One Accessories] melterx12:
all nexus one orders come with a charger. They also come with a usb cable, back-slip carrying case, and a headset.
[Nexus One Accessories] stewart1988:
Not when you want it shipped to the UK.

It adds a charger to the basket so I just deleted it

If it is in the box I'm guessing I will still get the US charger and can just use an adaptor to use in the UK.. :)

yeah youll get a US charger then. In any case all USB chargers are the same. if you have any USB charger with a USB port, you can jsut connect your included USB cable to the charger.
[Nexus One Accessories] cboy007:
this has micro usb i believe and the charger's you are talking about are all mini-usb. not compatible.
[Nexus One Accessories] melterx12:
this is not true. the side that connects to the charger itself is still all regular USB. both mini and micro USB cables have the same pinout and electrical output standard.
[Nexus One Accessories] cboy007:
i know. i'm saying that the end of the cable that plugs into his G1 will NOT FIT into the nexus one because it's MINI USB and the nexus one is MICRO USB.
[Nexus One Accessories] melterx12:
thats not wat hes asking. hes asking if an iphone wall charger (which simply has a standard USB port on the other end) will work.
[Nexus One Accessories] cboy007:
Ohhhhhhhhhhhhhh sorry
[Nexus One Accessories] wootroot:
i think your wrong with the "all usb chargers are the same"

my usb charger (micro usb) for my bluetooth headset will not charge a cliq, it its the same in appearance, but somehow it is actually different

however, the charging cable i had when i had a cliq charged my bluetooth, but I avoided it because it was obvious the 2 chargers where different.
[Nexus One Accessories] snofrandy:
correct. Certain chargers have different amp ratings. For example, GPS chargers generally require higher amount of amperage than cell phones, and certainly a lot more than bluetooth headsets
[Nexus One Accessories] ShyTownFantasy:
the g1 charger will not work with the nexus one. I have both phones. The behold II charger will work with a nexus one phone. my gf had the behold ii phone.
[Nexus One Accessories] snofrandy:
You mean plug-wise it won't work right? Because I just took my USB charger, took a Mini-USB to Micro-USB converter and used the G1 charger to charge the N1 and it works.
[Nexus One Accessories] ohwut:
I'm not sure about the Nexus One but I know on the N900 you could have the problem of that charger not supporting the Data pins(D+ & D-) to communicate with the device and establish a power draw rate, in which case the charger won't work with the phone. The solution was either clipping the data lines in the USB cable, or shorting out the pins in the charger. I doubt the Nexus will be that picky about chargers though.

Usb Charger

Hi,

I just have ordered mine from US. I am from Europe and i will definitely have the problem with the originally supplied charger.

As i am aware all usb ports works with the same voltage - 5V., only amp rate is different. We just need the output amp rate of the original charger and have to be careful not to exceed it. The smaller amp rates are OK (just the charging time will be more.

For example in the originaly stated data from Google says:

"Power and battery

Removable 1400 mAH battery

Charges at 480mA from USB, at 980mA from supplied charger"

Just one to confirm is the original charger amp rate 980mA as Google stated?
[Nexus One Accessories] jennyyu:
I think you'd better to buy a new mobile phone charger for your nexus one for safety. :)
