Here I post few Awesome Features Coming with Windows Phone 7 Mango!. But few more features coming with Mango update (WP 7.5). 1) Windows Live Messenger, Facebook chat and AOL Instant Messenger all integrated under Messaging. 2) Office 365 and Skydrive built into Office hub. 3) Group Messaging: currently there are some nice 3rd party apps that do this, but the ability to have pre-defined groups to message to will be now native, allowing to create quick groups for Family, Work, Friends, etc. ...
