Unfortunately, earlier this month, Vodafone canceled the planned global update. Citing a Wi-Fi problem identified in one of the “overseas” markets (we are not sure how to qualify that since Vodafone is a global carrier) while testing Windows Phone 7.5 MCR3, Vodafone indicated that they expect the issue to be resolved in a future update.
It would be interesting to learn what the problem was that Vodafone encountered considering that the Trophy 7's cousins in the US made a successful update Windows Phone 7.5 Tango. Alas, HTC 7 Trophy users on Vodafone must wait still longer. Hang in there!
