T-Mobile myTouch 3G HD (back)

We've already seen the mysterious (and as-yet unannounced) myTouch 3G HD, which is rumored to be T-Mobile's first HSPA+ phone, from the front. Looks like the same tipster fed TmoNews the back of the device. 

No word yet on if these pictures are real or if this is in fact T-Mobile's first HSPA+ phone. T-Mobile is keeping their lips sealed on this one, so it's likely we won't know for a while. But we're likely to see more of this before release, we reckon. Does the back of the phone change any opinions you had about the device prior? [TmoNews]
