What carrier/ one of the American carriers has issues (I think it's T-Mobile...) and sometimes needs an update through Odin on a PC.

my phone is under AT&T carrier, but i dont live in USA and i'm using a local provider (Algeria).

You can manually update the firmware using a computer. There are tutorials and guides all over the internet

is there anyway to get a version that is not affiliated to AT&T ? so i can get auto updates ?
