AT&T has now confirmed that commitment-free iPhones are going to happen — soon, in fact. As of next Thursday, you’ll be able to walk into the AT&T store of your choice and pick up an 8GB or 16GB unit for $599 and $699, respectively; that’s a little harder to swallow than the normal $199 / $299, granted, but in exchange, you’re free and clear without two years of your commitment.
