I got an AT&T unlocked S3(SGH-1747) about 6 months back and is on Android version 4.1.1. I chose to go with T-mobile and it has been working fine, but now when I try to update my software it automatically takes me to - AT&T Software update and since that is not my provider, I do not get any updates. How can I change this to T-mobile?
Thanks!
Thanks!
