Okay, I did a search, but didn't find anything specific to my question, so I did try Anywho, here's the scoop. We have 3 iPhones on a Family Plan, unlimited data, text, etc. They're all 8GB, 3G phones. My wife cracked her glass on the phone, and it works, but difficult to see, use, etc. Now, my phone is fine, but I qualify for an upgrade to my iPhone this month. The plan is that she'll get the new phone, but I'll be doing the upgrade with my number. Is there an issue with that? Or can I just oder it, have it delivered with no SIM, pop the SIM from her old phone out, and into the new one? I would think I could, but haven't found anyplace here, or on AT&T's site that says it would..or wouldn't...lol Thanks!
