On February 23rd the device will be hitting the shelves. Now just like on your original Vibrant, it's packing a 4 inch WVGA, Super AMOLED screen, a 1 GHz processor, also a 5 MP camera. What you're gaining, though, is a front-facing camera, T-Mobile's high speed 21 Mbps HSPA+ network and it's preloaded with the action movie Inception.
If this phone is what you're waiting for, then enjoy.
