The T-Mobile G2 has had its first live sighting, and it seemingly confirms what we suggested earlier in the week regarding the upcoming HSPA+ smartphone.  Engadget‘s tipster sent them a couple of photos of the handset, complete with T-Mobile branding, showing the G2 is basically the same as the HTC Vision.

That means a 3.7-inch WVGA touchscreen, slide-out QWERTY keyboard and an optical trackpad, as well as – we’ve heard – a 1GHz Snapdragon processor.  No word from T-Mobile on when exactly the G2 will launch, but they have promised more details in “the coming weeks”.

Update: Thanks to a second-set of images, we can now see the strange hinge mechanism that looks to lift the G2’s display up and over the keyboard, rather than sliding it straight up.  No word on tilting, though, like the HTC Touch Pro2.
