How to Unlock T-Mobile Galaxy S3 and Use On AT&T and WorldWide!

I know many of you were asking me this, “can you use T-Mobile Galaxy S3 on AT&T and as a world phone?”

The answer is yes, once you unlock your T-Mobile Galaxy S3, you can simply change its APN settings to use it on any network you want.   I do recommend trying Cellunlocker.net, you can unlock your phone for around $20-25 within an hour or two.

LiquidSmooth JellyBean ROM for Galaxy S3! [AT&T/T-Mobile/Verizon]

For those of you with AT&T, T-Mobile, or Verizon Galaxy S3, try the LiquidSmooth JellyBean ROM. Sorta of a hybrid between CM10 and AOKP, the LiquidSmooth ROM brings you a super-fast user experience coupled with many UI customizations you can be fond of. Besides that, the ROM itself is less than 100MB, making it one of the most lightweight custom ROMs out there and you can expect the ROM to make your phone darn fast without all the TouchWiz bloatware.

HighOnAndroid ROM v0.3 for T-Mobile Galaxy S3! [App2SD Hack Enabled][Custom Boot Animation][MOAAARRR]

Here’s HighOnAndroid ROM version 0.3 for your T-Mobile Galaxy S3!

The new version comes with App2SD hack enabled (you will need a FAT32 formatted SD card for this), custom boot animations, extended power menu, and 15 toggles.

The App2SD isn’t the standard App2SD, it’s a hack that “fools” your operating system into thinking the microSD card is the internal storage and vice versa. You can also disable this by either deleting the file in /system/etc/init.d OR you can also leave your microSD card on boot then re-insert once it’s booted completely for normal operation.

App2ExtSD – How to Save Apps to External MicroSD for U.S./Canadian Galaxy S3!

This is a hack that that allows you to swap internal storage with your external SD card so you can increase your app data storage.

All credits go to original i9300 App2ExtSD Hack by mattiadj. I simply hacked it to work with U.S. versions and also I’ve added code so it will disable this feature when you don’t have a microSD card inserted (app storage will default to internal when no microSD card is inserted).

HighOnAndroid ROM for U.S. Galaxy S3! [SGH-I747][SCH-I535][SPH-L710][SGH-T999]

So, I finally built the HighOnAndroid ROM for all U.S. Galaxy S3s including the AT&T SGH-I747, Verizon SCH-I535, Sprint SPH-L710, and T-Mobile SGH-T999. My plan is to start slow and perhaps add 3 new features every week. Anyways, currently these ROMs are all based off stock, gives you jelly bean animations, Google Now, and some other additional features you might like over stock.

How to Root U.S. and Canada Galaxy S3 AT&T, T-Mobile, Sprint/US Ceullar! [Fail-Proof][Noob-Proof]

So, you want to root your U.S. or Canadian Galaxy S3 with the Qualcomm dual-core 1.5Ghz CPU?

UPDATE: Please see updated root method here instead!

If your Galaxy S3 model started with SGH-T999, SGH-I747, or SPH-L710, you can follow this step-by-step guide and root your phone within about 5 minutes.  No, this will not erase any apps or settings on your phone and does not affect your phone in any way other than install ClockworkMod Recovery and give you root.  (So if you have problems after rooting, don’t just assume it’s from rooting, it’s not.)
