T-Mobile Galaxy S3 with AT&T Software
Hi there, for a long time i wanted to update my S3 from Android 4.1.2 to 4.3 or 4.4 but i can't i'm not in the US and i dont have it unlock so i see in the back of my s3 and says T-Mobile but the carriers app on the phone are from AT&T so i was wondering if the reason that i can update my phone is for not being unlock or for having a diferent android?
BTW, i found the stock update to 4.3 for AT&T users and i was wondering if i could installed?
I will really appreciate an answer!
