It’s evident that AT&T is on board as one of the carriers. Microsoft CEO Steve Ballmer and AT&T CEO Ralph de la Vega will be jointly hosting the conference to discuss the latest developments of Windows Phone 7, according to the press invite.

Despite Engadget’s report that T-Mobile will be a highlight of the Microsoft press conference, a Microsoft spokeswoman said T-Mobile is holding a separate press conference on Oct. 11 that is not part of the Microsoft conference. She declined to comment on whether T-Mobile would be among initial carrier partners offering Windows Phone 7.

Windows Phone 7 is Microsoft’s complete do-over of its mobile operating system previously dubbed Windows Mobile. Microsoft established an early lead on mobility with its older mobile operating system, but in recent years the company has suffered substantial losses in market share. Windows Mobile hasn’t been upgraded substantially in several years, and more user-friendly competitors such as Apple’s iPhone and Google’s Android OS have taken market share away from Microsoft. As a result, Microsoft scrapped the Windows Mobile project and redid the entire OS into a tile-based interface incorporating elements of the Zune media player and Xbox Live gaming.

Microsoft is also tackling its competitors on the patent front. On Friday, the Redmond company sued Motorola over alleged patent infringement in its Android phones, covering features such as “synchronizing email, calendars and contacts, scheduling meetings, and notifying applications of changes in signal strength and battery power.” And in an interview in the Wall Street Journal Monday, Microsoft CEO Steve Ballmer says that Android sales will generate licensing fees for Microsoft.

Though the company will announce details about Windows Phone 7 at the Oct. 11 conference, multiple reports have claimed that the official shipping date of the first Windows Phone 7 devices is Nov. 8. Wired.com has heard the same date from sources familiar with the project.
