David over at TMoNews has proof of the timing of an expected pending update for HTC’s QWERTY slider, the G2. The screenshot, of Magenta’s internal system, indicates that an over-the-air update will be rolling out to the HSPA+ gadget from November 3rd through November 8th. Included are Wi-Fi calling and tethering support, though reps are discouraged from actively discussing this feature with customers for the time being.

Looks like the flag is about to rise on Magenta’s 4G keyboard slingin’ flagship.
