[Samsung Galaxy S (4G Model)] creativedevil:
I doubt it, once unlocked it will work on all GSM carriers is true, but it is specifically built for T-Mobile frequency, AT&T has different frequency.

Similar to the situation we have in canada, Rogers Fido Bell Telus work on similar frequencies but Wind and Mobilicity work differently.

As Galaxy S 4G is meant for T-mobile, it will work 2g only with AT&T and for that sake with 4 major canadian providers too... :(
[Samsung Galaxy S (4G Model)] moshe22:
I would suggest to check what phones arw im at&t and check their specs and bands. Once you do that you will know wether it will work in at&t or not.

Sent from SGS4G
[Samsung Galaxy S (4G Model)] toasis2000:
Yes, I can confirm that it does indeed have UTMS band 1900, just like the Vibrant. I'm using it right now on AT&T and I do get 3G...now if only I could figure out how to enable 4G.
[Samsung Galaxy S (4G Model)] joedeveloper:
I can confirm that it works on AT&T 3G as well. You in fact get faster 3G speeds in some areas because AT&T has some different coverage than tmobile.

I unlocked the SGS4G for my Father In Law who is on AT&T, and it immediately connected to AT&T 3G. 4mbps/3mbps

It won't work on 4G though.
[Samsung Galaxy S (4G Model)] chaoslord1990:
thats becuase at&t dosnt have 4g yeat eventhough they have 4g phones
[Samsung Galaxy S (4G Model)] icy56:
Why not just get the vibrant instead of all it works on is 3g. It has much much more roms than this phone ever will especially with the release of the g2x and galaxy s2.
[Samsung Galaxy S (4G Model)] danstheman7:
Why wouldn't 4G work? It's on the same bands, and if you have all the APN info, shouldn't it work?
[Samsung Galaxy S (4G Model)] Longcat14:
Because AT&T hasn't made any tower upgrades to increase speed.

Technically, you are on 4G, but receive 3G speeds.

With T-Mo, you WILL get 4G speeds (10mbps+), because they have the necessary tower upgrades to make that possible.
[Samsung Galaxy S (4G Model)] corys00:
Anyone know where I can find a detailed (and updated) map showing which frequency is being used in specific areas? I'm [] this close to switch to AT&T and wouldn't mind using this until the iPhone refresh. But if I'm in 850MHZ area, I'll either trade it or sell it, as I originally intended to do.
[Samsung Galaxy S (4G Model)] danstheman7:
I'd skip out on switching to AT&T- they're terrible.

The 3G upload speeds are a joke, and coverage (at least in my area) is terrible. And don't even get me started on their Tech Support department.

As for the map though, I don't know of any public ones available.
[Samsung Galaxy S (4G Model)] danstheman7:
What kind of upload speeds should you be getting then?

I'm getting less than 50kbps upload....

(In AT&T Full 3G Coverage Area)

My download is always around 2MBPS, which is strange, because my iPhone 4 got around 4MBPS in the same location...
[Samsung Galaxy S (4G Model)] Longcat14:
With the upload thing, I may be wrong, but it's probably because they don't have HSUPA on.

And on the download thing with your iPhone, remember, your iPhone can take advantage of both 850MHz and 1900MHz, the GS4G can only take advantage of 1900MHz, so there will most likely be some variation in speeds.
[Samsung Galaxy S (4G Model)] danstheman7:
Ahh, I never even knew that it was only 1900mhz compatible on 3G D:

So, does that in turn mean that my phone will not work on AT&T's "4G"? Because that's the main point of me getting this phone over the Nexus S.
[Samsung Galaxy S (4G Model)] joedeveloper:
Here in Vegas and surrounding henderson areas my Father in law was getting 4.5mpbs down and 2 up so it's fairly consistent but we have good ATT coverage here as well as Tmobile (which I'm on 4G).
[Samsung Galaxy S (4G Model)] danstheman7:
I'd love to get speeds like that, but I'm in NY.

Worst.Network.Congestion.Ever :(

oooh and quick question, do you have a thread which has instructions to remove the "Pink" boot or shutdown screens?

Thankyou :D
[Samsung Galaxy S (4G Model)] joedeveloper:
Pretty straight forward if you are used to ADB or any other file managing software.

To disable shutdown just rename

/system/media/video/shutdown

to be like /system/media/video/shutdownbackup

For the startup screen look here:

http://forum.cyanogenmod.com/topic/...t-software-not-suck/page__p__36615#entry36615
[Samsung Galaxy S (4G Model)] danstheman7:
Perfect...Took some time to get it working (this is my first time using ADB), but looks great.

Thank you!
[Samsung Galaxy S (4G Model)] Longcat14:
Well, this phone has the hardware capable of 21mbps, and since AT&T is like T-Mo, and running their HSPA+ (4G) network of the same bands as their 3G, you will get their 4G speeds, once they upgrade their horrible towers (sorry, but T-Mobile 3G speeds are faster then AT&T 4G. xD ).
[Samsung Galaxy S (4G Model)] danstheman7:
I know it's true, sadly :\

Wish AT&T would upgrade the 3G towers in my area but I heard direct from ATT Tech support tier II that they have NO plans to do that at all.

WITHIN TEN MILES.

To think I live in such an urban area too.

bah humbug :P

Wish I could set up a 4G MicroCell, that'd be awesome.

Because as it is now, my download/upload is

right now

D/L:

.49MBPS

U/L:

LOLJK TEST WON'T EVEN FINISH (around .01MBPS)
[Samsung Galaxy S (4G Model)] Longcat14:
God, those are HORRIBLE LOL.

T-Mobile 3G is gonna be faster then AT&T LTE (believe me, they're gonna mess it up somehow rofl).

D/L: 5.25mpbs

U/L: 0.85mbps
[Samsung Galaxy S (4G Model)] danstheman7:
I know :\

And I have a feeling by the time AT&T finishes its' LTE network, Verizon will be on Advanced-LTE (or whatever it's called).

I'm honestly hoping AT&T is able to take over T-Mobile (it passes the regulators) because then it'd benefit me...I think...lol.

AT&T has ZERO 4G near me....and T-Mobile/Verizon have 4G/LTE (respectively) in my area. Wait...i said this already, didn't I :P

OOH MY DOWNLOAD WENT UP!

D/L

: 2.66MBPS

U/L

: .06 :(

Oh and the GPS on the Galaxy S freaks out too. Which is weird.
[Samsung Galaxy S (4G Model)] Longcat14:
I don't want the merger to happened, I like getting good download speeds. :(

Instead of shelling $39 billion for T-Mobile, why not spend that $39 billion on your towers, and watch them be so amazing, your 3G will be faster then Verizon LTE.

I also want T-Mobile to release HSPA+ 42mbps, and then Long Term HSPA+ or, if you want the exact download, speeds capable of 650mbps. xD
[Samsung Galaxy S (4G Model)] danstheman7:
650MBPS....ohboy. Definitely beats my 25/25 fios speeds at home lmfao

the day that happens, I cancel my AT&T contract (all 4 lines) and FIOS contract, and tether my phone to my computer, which then shares the internet to my whole house.

forthewin :D

But in AT&T's case....I'd agree with you. The merger really is a stupid idea, but if AT&T doesn't get this approved...they're not going to spend all that money on improving towers, or even spreading out their "blanket" (more like two strings) of HSPA+...they're just too cheap.

WANNA TRADE NETWORKS? :D
[Samsung Galaxy S (4G Model)] Longcat14:
Uhhh.... NOPE. >:D

Yeah, if T-Mobile does have the chance to get those speeds, that 5GB cap will be hit REALLY fast LOL. But I doubt they'd have that cap anymore with THOSE speeds.

They are trying to get rid of competition. Sad part is, all this is doing is making T-Mobile customers go to Sprint, so then Sprint becomes a real competitor (as if their not already, just a bigger customer base).

And at AT&T's HSPA+, I doubt ANY of their towers have HSPA+ upgrades. T-Mobile, having less money, less customers, and less EVEYRTHING, can upgrade their towers, and you pay less.

AT&T can burn.
[Samsung Galaxy S (4G Model)] danstheman7:
Well 650MBPS capable. And sadly, I know what you've said is right. AT&T also just doesn't care how fast their network speeds are, but whether the network simply works or not.

I had sprint a few years ago, and honestly I hated them. Now, I didn't have a smartphone at that point and I bet the network has improved, but even voice coverage was terrible.
[Samsung Galaxy S (4G Model)] KAsp3rd:
Actually given the fact that T-Mobile is currently owned and operated by Duetsch Telekom AG. It has the largest customer base. With Vodafone (owners and operators to 51% of Verizon) following close behind where's At&T isn't owned by a larger corporation.

Btw my HSDPA in Germany when I was there and had my phone thethered would actually hit over 1 MB/s not from a speedtest sight though. Never checked that.
[Samsung Galaxy S (4G Model)] Longcat14:
Yes, well I am talking about T-Mobile USA, not all the daughter companies of Deutsche Telecom AG.

1MB/s is like 15 mbps, so it pretty damn fast.
[Samsung Galaxy S (4G Model)] danstheman7:
Insanely fast, to be precise.
[Samsung Galaxy S (4G Model)] KrisM22:
I know this is old. I just put a AirVoice SIM in my SGS 4G and get good speeds, txt, and data(browser) but can't send myself a 50kb picture to test MMS - just says "sending". Did you ever get that to work?

Thanks!
[Samsung Galaxy S (4G Model)] getochkn:
First, make sure your APN is set properly for your carrier.

Then, try a different modem. Lots of ppl have been having good success with the LB6 modem here http://xdaforums.com/showthread.php?t=1941078
[Samsung Galaxy S (4G Model)] KrisM22:
Actually what i had to do was flash back to stock, find that it worked there, reflashed the erikmm's SlimICS V2 and now it works - same APN

Thanks, though!!! :highfive: (carrier is of course att.mvno for airvoice)
[Samsung Galaxy S (4G Model)] topshot:
What speeds are you getting Kris? I may look into air voice.
[Samsung Galaxy S (4G Model)] KrisM22:
my best test was about 250kbps. I got a couple at maybe 150kbps, but I don't run Speedtest much as it chews up data! I do find that speed is great for browsers looking at bus locations and times. I think at some point I'll get an att phone like maybe an Atrix. My reception is slightly better on att, but the SGS 4G and a bunch of other SAM phones are terrible on reception. The S III apparently finally is good. The Atrix is supposedly good.

What I did was get a few AV SIMs and activated one on the $10/mo and tried it out a bit before I ported my main number to another AV SIM, again, $10/mo. Today i spent $0.23 .
[Samsung Galaxy S (4G Model)] topshot:
Looks like you're in an area where they use 850 instead of 1900? I'd actually use data so want 3G speeds. I may have to keep the Captivate I was going to sell for when I go on vacation. I hate that T-Mobile drops to 2G anywhere between the 4G cities and has less coverage than either AT&T or Verizon (according to their respective coverage maps at least) who are 3G almost everywhere. Sounds like I should get a pay as you go plan and forward all my calls to the temp number.
[Samsung Galaxy S (4G Model)] KrisM22:
I'm in Boston, so I expect they've got the latest and greatest, or so. 3G is defined as 200kbps. My phone often shows H or 4G. This is bonus. But also why I want to get an att phone. (I just called and checked, and they do 4g on the $10/mo plan.)

Also note that I am using a rooted custom ROM and used "System Tuner" free to freeze all the google stuff, to get low data usage. Once i find my minimum, I'll start adding stuff to the budget point.
[Xoom General] Santoro:
I would love to Nexus One-like per-app color notifications on my xoom.. anyone know if it's an RGB LED?
[Xoom General] Oasisplayer311:
I use Kik Messenger and you can set different LED colors for the notification, I tried all colors and only white worked.

so my conclusion, only white lol
[Xoom General] Santoro:
That is good circumstantial evidence, but it is also possible that the LED is addressed differently in Honeycomb.... anyone know for sure?
[Xoom General] Kcarpenter:
Well, we do know that it does Red, White and Green. It could be 3 different LED's that produce these colors, but I would be doubtful. 3 cheap single color LED's are about the cost of one Multicolor LED, and it would be easier to write code to support one LED at different voltages than 3 on different channels.

Then again, the Epics Only does Red/Blue colors...never seen white but do occasionally get a purple...so maybe it has 2 LED's, a R/B and a White.

:D
[Xoom General] Santoro:
It sounds like you may be talking about the battery charging light. I am talking about the oblong white LED on the upper-right bezel. Have you seen that change colors?
[Xoom General] kcrudup:
The power LED is tri-color and uncontrollable in SW (other than being able to turn it on/off while charging), but the Notification LED is white-only. The /sys/class/leds files also bear that out. Its not an HC issue, but one of hardware.
[Xoom General] Santoro:
I was afraid of that. Dang. Thanks for the info.
[Xoom General] eaglecomm:
There is also another LED (I think) next to the front camera. When I attempt to power on the Xoom (after shut down) and I don't hold the power button in long enough.. I get a triple blink in red. Thats the only color I have seen, but never seen anyone mention that one.. just one more to hope for being in multiple colors. ;)
[Xoom General] kcrudup:
Yeah. Here's all the lights I could find:

# ls -l /sys/class/leds
lrwxrwxrwx root root 2011-04-08 12:10 flash -> ../../devices/platform/tegra-i2c.2/i2c-2/2-0053/leds/flash
lrwxrwxrwx root root 2011-04-08 10:38 lcd-backlight -> ../../devices/platform/tegra-i2c.0/i2c-0/0-002c/leds/lcd-backlight

lrwxrwxrwx root root 2011-04-08 12:10 torch -> ../../devices/platform/tegra-i2c.2/i2c-2/2-0053/leds/torch
#

Not sure what the MMC devices need LEDs for, but "flash" is the rear-camera's flash, "lcd-backlight" and "notification-led" are obvious, "privacy-led" is the one mounted near the front camera and IIRC "torch" is the LED that indicates you're recording with the rear camera.

From simple testing the only thing you can change other than on/off on any of these is the backlight brightness.

Also, the charging LED can be turned on when on the charger (but color and/or brightness is unchangeable) via writing a "0" to /sys/class/gpio/gpio168/value .
[Xoom General] TeeQ:
The LED next to the front facing camera is to indicate that the front facng camera is active AND WATCHING YOU!!!
[Xoom General] kcrudup:
Checked the kernel- turns out that's a "freebie" by the MMC host driver, in case you have an SD card in a reader; that would be the activity light.

I really hope someone can make something happen for us "stockers"
[myTouch 4G Themes and Apps] RavenWulf:
You don't flash those skins, they are .apk files... You install them as an app. Worse case scenario, you install and stock theme chooser doesn't show it.

that sux, I was hoping it would work but wasn't sure... side note I forgot to mention in my first post, if you decide to switch to a Sense ROM to use those skins it has to be a Sense 2.0 ROM such as the ones I listed, Royalmint or any of the other Sense 2.1 ROMs that have popped up lately won't work.

[HOW TO] activate JIT on 2.2

PEOPLE. NO OFF TOPIC HERE!

if you dont know what JIT is it basically speeds up your phone, very recommended! more info ---> http://en.wikipedia.org/wiki/Just-in-time_compilation

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Hi all! i know some of you want to test JIT complier... so i did a little research and found greek forum ---> http://www.myphone.gr/forum/showthread.php?t=286161

there our friend kyrillos13 has posted a way to activate JIT. so heres guide in english how to do it:

Activation Wizard of JIT

You need to install the root explorer (find it by searching on google). After the installation will take you to leave a message superuser. Press allowed. Download the file from here http://www.multiupload.com/9HK3NP4MML Unzip and copy the system folder on your memory card. With root explorer access the bin folder, select all the files and copy them to the path / system / bin / on your mobile. Upon return to the system folder that you copied to your phone and open the folder lib. Select all the files and then copy the path / system / lib / on your mobile. Then execute the commands listed in the file folder JIT instructions to download either via the adb pc or terminal emulator through the phone. Stir in and reboot. Download from the MARKET linpack do the install and run. If you pull MFLOPS 7 + (maybe even 11+) your ok. The linpack is optional. The jit will work anyway. just if you have doubts about whether you did it right then test it with the linpack (from market)...

the commands:

(adb shell) write this IF using ADB,

su

chmod 755 /system/bin/dalvikvm

chmod 755 /system/bin/dexopt

chmod 755 /system/bin/logcat

---------------------------------------------------

automatic batch script is the best way!!

-tested on: kyrillos 3.3 and 3.0, lestatious 1.7 with fugumod 2.2 BE, odexed JPM rom+fugumod 2.2, normal JPM, normal JPF, normal JP3.

[Galaxy 3 Android Development] ketotu:
Which task has the build.prop in /System/ ?

Everywhere you can read that you have enable Jit in this file,

but I can't see any difference if I write : dalvik.vm.execution-mode=int:jit

or if I erase this.

If I change the the heapsize, I can't see any differences too.

Can anybody tell me something about the build.prop ?
[Galaxy 3 Android Development] vonuzu:
Did u tried this? impressions?

GOOD JOB

Tried JASUX links, 8,3MFLOPs instead of 2,8 - good improvement.

Using Lestat 1.7, Fugumod 2.2 no OC

Quadrant improved from 320 to 380.

Edit: Jazux, I think you have to be more specific in first post about system demands for JIT - deodexed, rooted, base FW etc...
[Galaxy 3 Android Development] Mr.Gamer:
Jazux it's not the dev of the mod and probably doesn't know...

I think the jit is based on a JPM release, anyway if you don't wanna brick your phones (well, softbrick!) wait for apocalypse, this is experimental as everything in this forum :rolleyes:
[Galaxy 3 Android Development] zavisa:
Re

I tried but i got this msg...

Phone reboots and nothing
[Galaxy 3 Android Development] Urmas1:
Well, I was struggling to get JIT for three days before it came up here.

All I learned about JIT is that you have to have DEODEXED ROM and be ROOTED. This package of JIF is specific to our phones but do you have to be on JPM - I`m not sure. This may even work for Eclair. Until not tested can`t say. I`m not going to test it on Eclair or any other version and who does have Eclair anyway nowadays :D

If I`m wrong please correct me.
[Galaxy 3 Android Development] s3th.g3ck9:
You should mount your system writeable...

Is your phone rooted?

Damn, I was close to making it myself, would have probably posted it later today:P But anyways, great news. Now I don't have to do the work :P

P.S. same issue as zavisa. though on JPM, problem was probably that it wasnt deodoxed. will flash indroid now and try again
[Galaxy 3 Android Development] Urmas1:

[Galaxy 3 Android Development] Urmas1:
Hei Moole, source of your package is....?

Cos libs inside are same like Kiryllos ones. Did ARMV team released them somewhere already? Of course if they were same team they should have same lib`s.
