OK I have an employee plan and we are not allowed to have iPhones so I have a blackberry plan sim card. How can I put the blackberry sim into the iPhone and get all the capabilities that is offered with the iPhone without getting into trouble with att or Apple? I am in the USA in Kentucky, I have the 2g iPhone with the 3.0 update and it is jailbroken and unlocked. Is there a way to hide my imei from the man? I just want to use the iPhone with my plan but if not then it is no biggie.
