1) Can I buy an iPhone today, legally active it via AT&T/iTunes, buy a second iPhone a few days later, not activate it and simply move my sim card to the new phone and use it without going thru the activation again? 2) Can I later take the old phone (using the new sim that was swapped from the new phone) and activate it with a new number and new contract? Why??? - Im thinking on buying now, and switching phones when rev 2 comes out and give my old phone to my kid. I will need the new features and more memory, my kid wont need the new model.
