OK, I upgraded by 1st gen iPhone to 2.0 before buying the iPhone 3G. When I bought the iPhone 3G at AT&T, they took the sim out of my old iPhone & put it in the new iPhone 3G. They gave me the new sim that was in the box for the new iPhone 3G in case I ever needed it. Now, I don't know how to turn the old iPhone into an iPod Touch. When I turn it on, it tells me to connect it to iTunes. iTunes then wants me to activate it with AT&T, which I don't want to do. It won't just let me transfer music, etc. to it. HELP!
