It seems like only yesterday the T-Mobile G1 was released, but according to reports by Cell Phone Signal citing an anonymous tipster, G2 - the second HTC phone built for Google's Android platform - is well on its way. Apparently, the new device will be 3G capable, sport a full-sized touch screen, have a 5-megapixel camera with autofocus and flash, a VGA camera for video calls and come with the usual array of features you would expect from a high-end smartphone like Wi-Fi and Bluetooth.
Interestingly, there's no mention of any physical slide-out keyboard, which suggests the G2 will more closely mimic the iPhone - though there would still be a trackball at the bottom. The new device is also expected to be non-exclusive to T-Mobile and sold elsewhere around the world, albeit probably with a different name on carriers other than T-Mobile for trademark reasons.
The original rumor puts January 26 as the release date for the new device, which would probably bring some early adopter wrath down upon T-Mobile considering the G1 was released in October. However, the blog Boy Genius Report has a follow-up rumor that claims the G2 will actually be released in April.
