Default update this s3

guys my friend recently bought the galaxy s3 .t999 .i think the phone is unlocked because he is using it in india . and on a different carrier. the problem is that the phone is on 4.1.2 .i dont know where to find the rom for this model, or even whether i should update this phone .i mean i dont know if the phone is unlocked for the current firmware and whether it will still be unlocked after updating in or installing a custom rom. i have attached a photo of the about screen. rooting is not a problem. i need to know whether i can install any custom rom on it without locking it . and please if i can update it try giving me a link for the firmware

If the phone is working there, it must have been unlocked. You can update the phone and the phone will stay unlocked. However, you do not want to update to the latest 4.3 release from T-mo/Samsung. Too many problems with it.

If you really want, you could root it and just flash Rooted 4.3 rom ONLY from this thread. But that does need a custom recovery.
