T-Mobile tossing Samsung Dart into its lineup on June 15th?

Just as the name implies, this one almost zoomed right past us. The Samsung Dart is likely to show its face on T-Mobile within the next two days, according to some very official-looking employee docs uncovered by TmoNews. Given that it shares the same launch date as the HTC Sensation 4G, the entry-level Dart -- aka the Samsung t499 -- won't be getting much of the spotlight. Regardless, we still want to give this Android phone some time in the sun, as it still sounds like a decent choice for first-time smartphone buyers: full touchscreen, 3 megapixel camera, Swype, and Flash support. Certainly there's a lot of unknowns about this device, but we're expecting those gaps to fill as Wednesday draws closer.
