When Verizon releases their first Windows Phone 7 device, it will be based on the HTC Trophy. Some sleuths at a gaming site that tracks WP7 handsets, have found a Windows Phone sporting the MWP6885 model number, similar to the HTC Arrive. They located a PC93-1.0.xml file and have surmised that MWP6885=PC93 and PC 93=Pro. Yes, it certainly gets a bit confusing. The net is that Verizon will likely brand their device as either the HTC Pro or HTC 7 Pro.
As for a Verizon release date? The last rumor we heard was a June release date.
Do some research and edit this post. The Arrive and the Trophy are not based on each other and is not the same phone. Hint: physical keyboard.
Updated. The naming of HTC phones is mad confusing. If I understand correctly, there was speculation that Verizon would brand this as the HTC Pro. Yet, the HTC 7 Pro is actually the HTC Arrive. Hence, my confusion, but thank you for pointing it out.
Good news is that it’ll release as the HTC Trophy, if we can trust Best Buy.
