T-Mobile, HTC and Google converged on New York City on Tuesday to unveil the first publicly-available mobile phone based on the Google Android open source Linux mobile operating system.

The 3G touch screen device, which somewhat resembles T-Mobile's popular line of Sidekick devices, comes with a host of features and functions, and is based on open standards to enable the device to be "future proofed" as the mobile application ecosystem continues to grow.

Here are some additional photos and details of the T-Mobile G1, a suitable rival to potentially unseat the Apple iPhone for a shot at touch screen mobile device dominance.
