The next big update for Windows Phone 7 is codenamed “Mango” and will available as a free upgrade for current devices sometime this fall. One of unique new features that will be part of the update is called Threads. The Threads feature lets you integrates SMS text, Facebook and Live Messenger messages in a single unified threaded discussion. You can see an example of it in the screenshot provided by Microsoft.
Mango detects the current presence information for people in your contacts list (Facebook, Live Messenger, etc.) and helps direct you to the service that provides optimal communication between you and the other party for that specific time. Twitter and LinkedIn contacts information will be linked with Windows Phone’s contacts to further integrate communication across social networks.
