I was one of the first to receive an HTC Wizard/T-Mobile MDA device and posted a full review on Geek.com a year and a half ago. T-Mobile was the first in the U.S. to update or release a device running Windows Mobile 6 when they released an update for the T-Mobile Dash and today they announced the release of a Windows Mobile 6 Professional (aka Pocket PC Phone Edition) device called the T-Mobile Wing. This device was revealed just a couple of weeks ago by the FCC and it didn't take long for T-Mobile to get it out. The press release and device specifics haven't even been posted on T-Mobile's site yet, but a couple of fellow mobile enthusiasts have full reviews that you should check out for more information. Mobility Site and Mobile Tech Review take the Wing for a spin and for the most part are pleased with the device. It lacks 3G since T-Mobile is the only major U.S. carrier without this service so that is one area of concern. It does have WiFi and Bluetooth, but also uses the 200 MHz processor like that used in the current T-Mobile MDA. This is fine for Smartphones, but a Professional device really should have 300 MHz or more under the hood. That said, I have some gadget cash saved up and may be adding the T-Mobile Wing to my collection soon.
UPDATE: Pricing looks to be US$299.99 with 2-year contract and US$499.99 without. It should be available in stores at any time and I may have to swing by T-Mobile and check it out soon.
A couple more reviews and videos have appeared and I was pleased to read that the phone quality was so good. Check out these reviews for even more details.
