I got waaaaaaaay more back then i originally thought!! and I was thinking of buying an iPhone. I am confused to what I've heard about buying just an iPhone outright without a contract. Is it worth trying to find one on craigslist or eBay versus buying directly from apple?? Also since I'm not using it on a cellular network, does it matter if I were to get a 3G or 3GS? I plan on jailbreaking it, and I know there are certian apps that enable video on a 3G etc...is it true that the 3GS is harder and in some cases not jailbreakable? Thanks guys!
