Hi
Sister is buying my 3g iphone and said i can have her old one off her its from the states has been jailbreak and unlocked as she is on T-Mobile, my question is can i update the firmware on this iphone.
As its from the usa it will be using the AT&T network i guess so i was wondering when i get it if i reset it and update will it no longer work as i have a O2 sim in ? or will i be able to unlock it etc to work again with O2.
