If you wanted to buy an iPhone off-contract, Erica Sadun over at The Unofficial Apple Weblog notes that it makes more sense to get on with a contract, then cancel the contract. Even after paying the $175 early termination fee, and paying for the first month of service, at about $450, she says, you’re still money ahead versus the $599/$699 off-contract prices. But who’d want to do that? Someone who wants to jailbreak their phone for use on other networks and with unapproved applications, I guess.
