Windows Phone Mango Release - Finally Upgraded

After several attempts, I finally got my Windows Phone 7 updated to the Mango release.  It kept failing and reported an error C1010007.  That error indicates that the cable is bad or not the original cable.  I finally tried again and kept touching the phone every minute or two.  The upgrade continued and finally finished.  I suspect the phone goes to sleep during the upgrade. 

Hope this helps others upgrade easier.  It's something to remember for the next upgrade.
