Sure there's only half an hour or so until T-Mobile unveils the world's first commercially available Android handset, but heck, this is tech blogging--clearly we can't wait until thing like official releases.

The service provider has apparently leaked some promo shots of the handset's OS on the official G1 site.

The images don't look to be too far removed from what Google has been showcasing all along, with a few T-Mobile-tailored features like the MyFaves icon. For those who can't wait the extra half hour, check out more images at Boy Genius Report.
