As you may have noticed on the Windows Phone Team Blog. They have announced that the Mango Update will start rolling out in the next two weeks. http://windowsteamblog.com/windows_phone/b/windowsphone/
Now is the time to get your applications ready. If you have not already downloaded the Windows Phone Tools for Mango make sure you do it now by going here http://bit.ly/wptools1
Once you have them downloaded, give me a shout on twitter @DanielEgan if you have any questions (@reply not DM).
