Hello and good afternoon, I just have a quick question, when you sell or give your 1st generation iPhone to someone, is there a specific way to do it so that you maintain your upgrade eligiblity? My wife and I are on a family plan, I'm planning on giving my iPhone to my wife, does she use the sim card I currently have in the iPhone? will she have to get a new sim card from AT&T?? How do I go about giving it to her so I don't lose my upgrade eligibilty?? Any help that can be supplied will greatly be appreciated.. Thanks in advance..
