Long story short, I want an iPhone 4S & need to buy one without a contract. Obviously, I can't afford the $500-whatever to buy through a carrier without a contract (even if we had that kind of money, I couldn't justify that for a phone). So... I'm thinking of getting one on eBay. They have their recommended/verified sellers that I could look at with a Guarantee policy... I'm still a little nervous about the idea. Any thoughts? Suggestions?
