I have 2 8GB iPhones on a family plan, one I sold and just put the sim card in storage, the other I sold and put the sim card in a cheap phone I had lying around. I have not done anything with at&t as far as canceling the iPhone data plans, At&t still thinks I have an iPhone on the account that I have done nothing with the sim card. On the other account it shows that I have my cheap little phone in the online picture... Does this mean that I can get the subsidiary on both lines, or just one of the lines. AT&T reps have no earthly idea what is going on... So I would see if you guys do... Thanks!
