A Samsung phone labeled the SGH-T959V has just paid a visit to the FCC and it’s speculated that this phone is T-Mobile Vibrant 4G. What makes us guess that it’s the Vibrant 4G is the fact that the original Vibrant featured a model number of SGH-T959, which is almost the same as this. The phone supports AWS, which is needed for a T-Mobile 3G/4G device. Aside from that, the outline of the phone does look similar to the Galaxy S and it’s variants, doesn’t it?
