Hi guys, I searched for my particular situation but wasn't able to find anything specific enough and am posting a new thread as a last resort. My brother and I both pre-ordered the 4S online. He bought his from apple.com and I bought mine from AT&T's website. The thing is, he does not live anywhere even remotely close to an Apple Store but he does live pretty close to a few AT&T retail outlets. We are wondering if it would be possible for him to take my phone (the one ordered via AT&T) and for me to take his phone (ordered from apple.com on his AppleID) and keep our phone numbers. Both of us are upgrade eligible so we don't have to do any upgrading on different lines. Is this a regular upgrade swap? If so, do we just take out the SIMs from the two phones and change them before we turn either phone on? Or can we just turn on the phone and type in what number we activate the phone on (he would take my phone and put in his number and vice versa) or is there something completely different that we have to do? Thank you for taking the time to read my question and I do sincerely apologize if this has been posted before and I was unable to find it. I know this forums sees tons of new threads near a product launch and I did try to find the answer before contributing to the logjam with a new thread. Thank you again.
