T-Mobile's newest 4G offering, the Samsung Exhibit 4G, made its way through the FCC, and posed for the cameras too. Its official model number is SGH-T759, and may have the following rumored specs:
  • Front- and rear-facing cameras (with an LED flash)
  • A microSD card slot
  • Android 2.3.3 with a TouchWiz veneer
  • An HSPA+ radio.
  • 3.7-inch Super AMOLED
  • 1.4GHz processor -- maybe the older ARM11 variety
