Well I posted on Craigslist to see if anyone is willing to trade their 16G black iPhone 3G with my 8G iPhone 3G (with me paying the $100 difference) and I'm getting tons of responses to sell my iPhone to them for $300+ instead. I am sort of willing to do this also because I wouldn't mind standing in line for 1hr+ to get an iPhone again (altho the employees might recognize me and give me weird looks). But what I'm wondering is if this is legal or not? What will happen to my AT&T account then? Can I just pop out my SIM card and stick into the new one that I'll buy?
