Vibrant 4G that we know is on its way to Big Magenta before too long. Why's that? Well, most notably, SGH-T959 is the model number for the original Vibrant -- and like the Vibrant, this device has support for AWS, which any T-Mobile 3G / 4G device would need. Furthermore, take one look at that outline up there -- certainly looks like a Galaxy S of some sort, doesn't it? More on this soon, we suspect.
