If you're not aware of the event already, Microsoft is holding a Windows Phone 7.5 (Mango) preview in four days, and invitations to the press are now being received. In keeping with the fun nature of the OS, the invitation for the event is a fairly large surprise. A real mango in a box.

If you're not up-to-speed with all the goings-on surrounding the next major update for Windows Phone 7, you can take a gander at our past coverage of upcoming Mango and tune in Tuesday morning (10 EST) for our live coverage of the event.
