Someone gave me their old 2G iphone, and the SIM card that was used. They now have a 3GS and new SIM. OK, so it's in emergency mode, connect to itunes, blah blah. But when I put in the old SIM, connect to iTunes, it wants to set it up as a phone with his number! How can I just use this thing as an iPod touch? I do NOT want to jailbreak/hactivate.
