Hello guys this is my first post and I apologize if I am posting this in the wrong place. I am just a bit worried since I live in another country (Costa Rica). My concern is, if I buy an unlocked AT&T Infuse 4G from amazon can I still get the official GB update?? I hear that, for example, you need to register on the AT&T site but if the phone is unlocked I assume there is no registering :-\ Or is the update available to me OTA either way? Any help with this concern will be greatly appreciated Thanks!
