Well as you know or some of you do, my iphone is toast. So it is jailbroken and bought from a freind. But apple dosent know that. THe genius ran the serial number and said in order for a swap they need the sim card the phone came with. But i do not have it....the sim card is in use by the guy i bought it from so i am unsure on what they want. Do they want to jus see the sim and make sure i have it or they want to keep it. But if they want to keep it and i tell my friend i need to borrow it are they going to give it back. Im very unsure on what they want. Someone help thanx.
