Microsoft have started to rollout the 7740 firmware update for the HTC HD7 (Update: and the HTC Mozart ) on the Telstra network. Rather ironically this update is being pushed out a a day after Telstra delisted the phone from being able to be purchased from their web site (see http://madprops.org/blog/windows-phone-7-in-australia/) .

The update will be prompted for installed when you connect the phone to the Zune desktop software.
