Hi, a cdma iPhone 4 does not use a SIM card, the cdma iPhone 4s however does have a SIM card tray. Sprint uses cdma radio waves (it is waves i think but someone will put me right if not) not GSM radio waves although being from UK i don't have any more info as to tinkering with it to accommodate your sad loss of cash. I'm afraid you wasted your money. EFF rules KO!!
