At the Mobile World Congress in Barcelona, Microsoft announced it is adding new features to the Windows Phone 7 operating system.

Windows Phone 7 marked the entry of Microsoft after its initial attempts with the Windows Phone 5 and 6. The operating system debuted to generally positive reviews, though the lack of a cut-and-paste function drew some criticism, as well as its lack of native support for multitasking.

New features and apps include:

  • IE9 will be available for Windows Phone 7 in the second half of 2011 for an enhanced mobile Web browser experience.
  • Copy and paste is coming next month.
  • Support for Office documents in the cloud in 2011.
  • New multitasking applications in 2011.
  • Twitter will be integrated into the People Hub in Windows Phone 7.
  • New SkyDrive support services will offer users the ability to access cloud-based Microsoft Office programs via a phone.
  • Xbox LIVE Extras will allow users to customize their Xbox LIVE avatars from their phones, including the ability to add accessories and change styles.
  • Pac-Man, the classic 80s video game, will be brought to life on Windows Phone through Xbox Live. Tetris is also going to be featured and is predicted to be one of the biggest games on Xbox LIVE, along with Full House Poker, which allows bettors to play Texas Hold 'Em against thousands of players worldwide.
