AT&T has always seemed to have an odd relationship with Android.
Conspiracy theorists like to believe it’s because of the iPhone, and
there might be a little truth to that. But despite a slow start with
Android -- and a few odd decisions along the way -- AT&T’s started
to come into its own, sporting compelling smartphones from most of the
leading manufacturers. And it’s second out of the gate with the Samsung Galaxy S II.
The Atlanta-based carrier’s doing us all a favor by not messing with
the phone’s name at all -- the same can’t be said for others -- and
AT&T’s also shaken up the U.S. GSII lineup with some physical tweaks
to its Galaxy S II. Minor modifications to the software and user
interface hardly are a surprise, too. This one's pretty simple: The AT&T Galaxy S II, like its Sprint
counterpart, is running Android 2.3.4, with the latest version of the
TouchWiz user interface atop it. You've got the same look and feel as
you do on the Sprint version, and largely the same as on the previous
generation of Samsung phones. AT&T's done a fairly lackluster job in customizing its
homescreens. There's no real sense of purpose to the widgets that have
been included. Weather would arguably be one of the more important
widgets, but it's relegated to a second screen. Instead, you have the
Google search widget (while important, the search button on the phone
takes care of that), and that pretty useless tips widget. There's also a
widget for AT&T's featured apps.

- Backup APN Settings: GPRS, 3G, MMS Settings. How? Note down everything from: Settings > Wireless & Networks (More…) > Mobile networks > Access Point Names.
If you already have a custom recovery (ClockworkMod, TWRP etc.) installed on your phone, we strongly recommend a backup using that as it creates a complete image of your existing phone set up.
A few more optional tips that you should remember:
1. Having problems connecting your Android phone to the computer? You need to enable USB debugging mode.2. Make sure your Android device is charged up to 80-85% battery level. Why? Because, if your phone goes off suddenly while installing a custom ROM, flashing an official firmware update or installing mods etc. — your phone might get bricked or go dead permanently. No one wants that, right?
3. Most of the tutorials and how-to guides on MyTrickSource are for factory unlocked Android phones and tablets. We recommend NOT to try our guides if your phone is locked to a carrier, unless we have specified the carrier name or device model.
