How I sold my old iPhone 3G for double what I paid for my 3GS

Some people may not realize how much their old scratched up iPhone 3G is worth. The 3GS is out and I wanted it pretty bad for 2 reasons: 1) I’m an iPhone Developer. 2) Video recording. I’d had my 3G since right after they came out (actually waited in line here a bit in SF) so I wasn’t sure how much an upgrade would be. After only about a year I was elligible to get a 3GS 16GB for $200. I’ve talked to a few other 3G owners and everyone has been elligble for a $200 3GS.

So, I bought the new unit for $200. Before I made the purchase I checked ebay to see what used 3G 16GB were selling for. Low and behold, jailbroken, unlocked phones were selling for $400 or more! And these are USED phones. My phone never had a case and it had it’s share of minor scratches. Anyway, you can jailbreak and unlock the phone in about 30 minutes (you may have to torrent some software), then put her up on ebay. I just sold mine for exactly $400. A net profit of $200 for a brand new iPhone 3GS. Not bad… I may regret it on the next upgrade if I’m not elligble, but somehow I doubt it.

Here’s how you can do it too:

  1. Check prices on ebay
