Yesterday Microsoft Windows Phone Team announced the availability of Windows Phone 7.8 to existing Windows Phone 7.x family of devices by early 2013.

Some of the interesting features announced are:

  • New Customizable start screen with resizable Live Tiles.
  • It doubles the number of theme and accent colors—to 20—so you can make your phone even more personal.
  • There are also new lock screen features: the option to automatically display the Bing Picture of the Day plus the ‘A1B2C3’ PIN/password challenge to prevent accidental device wipes on phones connected to Exchange accounts.
