I’m going to buy 2 iPhone 3G s from craigslist from two legitimate sellers that got the new iphones. They restored the iPhones completely, but the “Connect to iTunes” message is on the screen now. I’ve heard the only way to get it to work is by putting an AT&T sim into it and plugging it into iTunes. I will be unlocking these phones for use on T-Mobile, that is why I am worried. Should I be?
