ok so i just got my 3g iphone and cant use it and its killing me... my parents are divorced and my mother got me the phone and sent it down to me and i just got it... i plugged it in to charge it and its keeps saying theres no service no matter where i go... i think i messed up when i first plugged it in and synced it with itunes becuase i clicked cancel instead of go back so its not tied to a mac id account... does anyone know what i can do to fix this???? i need some help!!!!!!
