Have a look at the T-Mobile myTouch accessories and benchmark scores
On another note, T-Mobile myTouch has been benchmarked already - thanks to its next-gen 1GHz Snapdragon inside, the handset scores 1890 on the Quadrant test, similar to what the HTC Desire HD fares with the same chipset.
Of course, synthetic benchmarks are just to prove a point, and how the phone will behave in real life, is another story. There is also a screenshot of the Wi-Fi calling feature floating around, as if to enforce the notion that the T-Mobile myTouch will be one of the more exciting devices to get the upcoming holiday season. Now we just can't wait for November 3rd to ring in.
