A car dock would seem more useful than a “swivel dock” for your desk. Be that as it may, T-Mobile has announced the latter of the two for US$49.99. Just as we suspected, the gold-dots on the myTouch 4G function just like those on the Nexus One, passing power from the dock to the device, and I suspect letting the device and the dock communicate via Bluetooh.

Further details are unknown, and the T-Mobile myTouch 4G accessories page is disappointingly sparse.

Does this look like an accessory you’d buy for your myTouch 4G? What other accessories are you hoping for?
