Hey Gang, Can anybody recommend the easist most pain free way to sell my iPhone 4? I saw this: http://www.cashforiphones.com Is this place legit? 32 GB iPhones are worth 580 bucks to them. Anybody ever use them? What about the SIM in iPhone4? Its not easily removed, but do I have to remove it? Also, I'd like to port my number, but I'd really like the cash from my sale towards a Verizon iPhone. So, since the phone would still be 'live' I'm assuming I have to pull out the SIM? Thanks in advance.
