Hi, ok so I JUST got home with my exchanged iPhone 4 due to some screen problems. They sent me off and I was happy. When I finally came home and hooked it up to iTunes, I found out that I need a SIM card to activate my phone to iTunes. This is where the problem is: I don't have a SIM card because I was using as a iPod until the jailbreak/unlock comes out. Please give me an answer that DOESN'T require me to jailbreak or go buy a SIM card. Thank you so much!
