No More Prepaid GoPhone Plans for the iPhone
According to a TUAW article by Erica Sadun, anyone using AT&T's prepaid GoPhone plan to avoid the 2-year contract will be forced to switch to a normal contract to maintain 3G data access. It's unclear how many iPhone users have jumped through the necessary hoops to use a GoPhone plan, but if you're among that group, you might want to upgrade to an iPhone 3G S just so there's some upside to being forced into a 2-year contract.
