Good news for those on Vodafone in Australia: the carrier has approved the HTC update that will enable WiFi internet sharing on the 7 Trophy, this just weeks after announcing that they were testing it:
Windows Phone 7.10.7720.68
Maintenance Release MCR1 (Internet Sharing Update)
Vodafone has granted technical approval of a new maintenance release. Roll-out will begin soon; keep an eye on our blog for further details.
This is excellent news as HTC certainly seems committed to their customers in getting this update to as many devices and carriers as possible. We'll keep an eye out for when it goes live.
