Looks like the rumour has panned out as businesswire post the announcement of the Dash 3G going to T-Mobile. The T-Mobile Dash 3G has previously been known as the Maple S522 and even the Sprint destined HTC Snap.
Spec wise the T-Mobile Dash 3G is decked out with Windows Mobile 6.1, has GPS, features 802.11b/g WiFi, full QWERTY keyboard and comes in black with red accents.
The T-Mobile Dash 3G is expected in July but so far there has been no word as to what price tag it will command.
