I wanted to unlock this and was wondering if this is possible. I went through lot of threads on this forum, but that left me confused and could not figure out if it is possible or it is not possible, without calling AT&T or without buying the unlock code.
There were some threads which said that we can go back to 4.1.1 or something. (I have been able to unlock the other phone which is running 4.1.2 but for this I cannot go back).
I am a newbie with phones and andriods, and hence was looking for simple instructions if any available to lock this 4.3 andriod that I have.
Any help would be greatly appreciated.
