We've heard that Magenta's flavor of the Galaxy S might launch early. And now, T-Mobile has created a Samsung Vibrant entry in their online store, though the device cannot currently be purchased. There is no official availability date listed in the online store.
The product page offers up official specs, a few of which have been a matter of contention. Here's a run-down/refresh:
16GB of internal storage with a 2GB microSD (supports 32GB of microSD space)
4â€³ Super AMOLED display
1500 mAh battery
