Less than two years ago T-Mobile, Google and HTC kicked off the Android revolution with the launch of the T-Mobile G1. The G1 was the first phone to run Google’s fledgling Android operating system and, just as with Google’s own brand Nexus One, HTC took over manufacturing duties. The device launched exclusively on T-Mobile (though it was later released network free as the HTC Dream) and combined a full touchscreen interface with a slide out Qwerty keyboard. And now, T-Mobile look set to release a sequel in the near future with the T-Mobile G2.

A teaser site has popped up on the world wide web allowing eager punters to sign up for updates on the upcoming Android phone though the site gives little away in terms of specs. The only tidbit of information we can actually ascertain from the micro-site is that the device will operate on T-Mobile’s 4G HSPA+ network in the states. Does this mean the phone wont make it over to this side of the pond? We’ll have to wait and see…

Well, time for some speculation. If we look at the original device, the G1, we can see that the HTC manufactured device sported a side sliding Qwerty keyboard and full touchscreen UI. Looking to the rumour mill, there is an upcoming phone that fits this bill; the HTC HD Z (formerly the Vision). Could the T-Mobile G2 be a network specific version of the upcoming Desire HD Z? Well, with a rumoured 1 GHz processor, 3.7 inch AMOLED touchscreen, Android and a 5.0 Megapixel camera with 720p HD video capture on board, we certainly hope so. Stay tuned on the Blog and we’ll bring you more on this story as it develops.
