We've heard rumors, but now it's for real. Windows Phone 7 will be launching on October 11 with a big event in New York. Of note here, is that T-Mobile, not AT&T will be front and center at the launch. We've previously heard that AT&T would be a big name in Windows Phone 7 devices, but T-Mobile's participation seems to indicate they will have some top tier phones as well.
Windows Phone 7 is Microsoft's attempt to get back into the mobile game after years of faltering with Windows Mobile. WinPho7 will use the new Metro UI emphasizing its live home screen tiles. Microsoft is also aggressively pursuing developers to fill out the app catalog. The new OS may be missing some features of its competitors at launch, many are impressed with what's there in the beta builds.
The launch event will be happening at 3:30PM EST on the 11th, and will consist of showing off some new Windows Phone 7 devices. Excited?
