Microsoft has officially launched Windows Phone 7 at public event in Barcelona. Windows Phone 7 is not something related to Windows OS. It's a next generation Windows Mobile OS which was unveiled by Microsoft CEO, Steve Ballmer in his 2010 Mobile World Congress keynote. At mega event in Barcelona, Microsoft unveiled nine WP7 handsets which would be available in selected European and Asian markets on 21st Oct and others market including US in early November.

Microsoft is all set to unveil a series of Windows Phones 7 devices in coming month. If you are planning to get hold of a Windows Phone 7 device and you use tethering regularly, you may think again. Windows Phone 7 based new smart phones will not support tethering.

Bing App for iPhone and iPod Touch has been released by Microsoft, application is also available for Windows Mobile and BlackBerry mobile handsets. It's a very handy iPhone app, it will certainly improve Bing search engine usage, as iPhone is considered one of the most popular platforms these days.

An interesting trademark application unearthed by Long Zheng suggests that Microsoft might be working on a new platform and content distribution system for its mobile devices. While Long believes it to be an AppStore for Zune HD, I think it just might be a re-branding of the Windows Marketplace for Mobile.
