Windows 7 Phone Oct 11 [online.wsj.com]

On Oct. 11, Microsoft and its partners plan to announce the initial wave of handsets that will use Windows Phone 7, a thoroughly overhauled version of the company's cellphone operating system. Mr. Ballmer believes the software will compete more effectively against Apple Inc.'s iPhone and Google Inc.'s Android operating system. Microsoft has gotten more aggressive against Android in other ways. The company filed a lawsuit Friday against Motorola Inc., alleging the handset maker is infringing Microsoft patents in its Android phones. Motorola vowed to fight the suit.
