Take this one with a grain of salt because according to a Verizon chat-room rep the WCDMA HTC Trophy Mango update will be pushed on the same day as AT&T; September 27th. Once again you should take this with some caution knowing that support folks usually don’t know much about theses kinds of stuff. In either cases you can already update your HTC 7 Trophy if you are in Europe or in the US on Verizon by
flashing with the final Firmware which has leaked a few days ago (edit: nope, looks like Verizon’s final firmware is newer than the one that leaked!).
