hi i was wondering if THREE NETWORK USERS UK can help me. I am currently on a three network contract 18 months and i really want a iphone 3gs and i wanna unlock it and place it inside. Can i make and recieve calls? Can i make and recieve sms? Can i get the 3G network? Will the network be good and usable? Would Three Network do anything if they know i am on the iphone 3gs?
