The tweet says it all. The update was posted by Chris Anderson, editor of Wired. Perhaps he is baiting us but nevertheless it’s the first rumor of its kind so what the heck.
Apparently Chris was told by a T-Mobile manager that the iPhone 3GS would be coming to the carrier. Why the company would be getting the year old model of the iPhone instead of the current device is beyond me. I guess that’s why they call it a rumor.
