The gang from TMoNews has managed to acquire several documents detailing what the next iteration of T-Mobile’s Samsung Vibrant — the Vibrant 4G — will entail. The report notes that the device will have a 4-inch Super AMOLED display with a 480 x 800 pixel resolution, 1GHz processor, 1GB of internal storage (16GB micro-SD card included), 5 megapixel camera without a flash, front-facing camera, and 1650mAh battery. The Vibrant 4G will earn the latter half of its name by wielding a 21Mbps HSPA+ radio. According to the intel, the device will run Google’s Android 2.2 operating system, not the more current Android 2.3. The addition of a front-facing camera and high-speed HSPA+ radio are nice incremental upgrades, although we’re not sure how this handset will look after Sammy announces the successor to the Galaxy S next month at Mobile World Congress.
