Recently, we told you that Microsoft will launch the Windows Phone 7 device in USA on October 11th, and the rumors were true. Microsoft came out and they officially announced that they will be launching the Windows Phone 7 in USA on October 11th, but not with AT&T. T-Mobile USA is the first one to unveil WP7 devices in USA. As you can see in the image above that “an exclusive showing of T-Mobile powered Windows Phone 7 devices”. Did you see devices? Which means that we are going to see more than one device on the launch. I am sure that the HTC HD7 is one of them, and HTC Schubert(1,2) too. Want to attend the event? Then head over to Microsoft if you want to note the address and time.
