Pocketnow have just posted this picture which purports to be HTCâ€™s first LTE Windows Phone 7 handset.
The device still has a massive 4.7 inch screen, but appears subtly thicker, likely to accommodate a larger battery to power the LTE radio.
According to earlier leaks the handset is not expected to reach AT&T stores at the same time as the Nokia Lumia 900, which is rumoured for an 18th March appearance, but will show up on AT&T some time afterward.
Pocketnow notes that according to their tipster this device will not be confined to USA, but should also hit antipodean stores on Telstra Australia.
