Not long after it pledged to update the myTouch 3G to Android 2.1, today a leaked document from T-Mobile revealed that the carrier is planning to further kick it up a notch with the release of Android 2.2. In addition to that, myTouch 3G owners will also get an updated version of the Faves Gallery alongside the addition to the Genius button and support for Exchange. No word yet on when the update will actually drop, but we imagine this update will involve at least a little bit of an agonizing wait.
