Last week Microsoft presented me with a Samsung Focus smartphone that was running a recent pre-release build of Windows Phone "Mango." Mango is the version of the OS that will replace Windows Phone 7, which launched last year.
Microsoft will release its first major update for Windows Phone, bringing more than 500 new features to the OS. Known up till now as Mango, the update will formally go by the name of Windows Phone 7.5 and focuses on improving three key areas: Communications, apps, and Internet.
I found some great features windows 7.5 (Mango) which are listed as per bellow.
