An advanced HTC Windows Mobile smartphone could make a rare appearance at T-Mobile if leaked firmware reflects the provider's plans. A ROM for the "Rhodium," the Pro2's codename, mentions T-Mobile by name and gives it the same US country code that identifies other HTC phones on T-Mobile, including the Dash and the Shadow. Supporting the claim is a mention that the phone's language on this release is "USA" rather than Britain.

While it hasn't touched on this latest leak, HTC has separately confirmed a US arrival for the Pro2 that would ship the first examples to the US in late spring. No carriers were mentioned at the time; it's also uncertain whether any T-Mobile edition would include native 1,700MHz 3G or else would be related to EDGE and Wi-Fi.

The Pro2 is considered a major update to the original and centers on a 3.6-inch, 480x800 touchscreen. It also has a 3.2-megapixel camera, GPS and an improved version of HTC's self-developed TouchFLO interface. [via pocketnow]
