I just sold my ipad 3G on eBay sans sim card (i'm using it to power a 3GS) and the buyer is demanding I send my sim card to him. He says it won't function without one and that apple and AT&T won't issue him a new one. Has he got a case? I don't see why I should hand over a sim card that has been paid for up until the end of the month, plus, don't sim cards hold personal info? My listing didnt mention the sim card coming with it, then again it didnt mention it wouldnt come with it. anyway, ive offered him a refund, just wondered who is in the right/wrong.
