Spy shots of the T-Mobile G2, also known as the HTC Vision outside of the US, have turned up for all to see ahead of an official launch from T-Mobile in the US.

The two shots tell us virtually nothing, but do show that the phone will feature a 3.7-inch display and a sliding keyboard with a design that is considerably smarter than the myTouch 3G Slide, and of course the original Android handset the T-Mobile G1.

This is the best spy shot of the handset to date, even though it's still pretty blurry, and comes just days after T-Mobile in the US launched a teaser site for the new G2 handset.

That teaser sign up page promises the T-Mobile G2 to "deliver tight integration with Google services and break new ground as the first smartphone designed to run at 4G speeds on our new HSPA+ network".

T-Mobile has promised to share "more details about the G2 and offer exclusive first access to current T-Mobile customers" in the coming weeks.

It looks like someones might have just gone and spoilt the surprise.
