While the Dell Venue Pro has been discontinued, we were surprised to see the Windows Phone receive the 8107 update pushed out to the phone. It was equally surprising today to see the Tango update hit the unlocked Venue Pro. While forcing the Tango update on the Samsung Focus S, we connected the Dell Venue Pro up to the computer and sure enough, the update notices appeared on the screen.
There was no need to force the Venue Pro to recognize the update and the previous updates to Tango (7740, 8107, etc) were installed first. Needless to say, it has been a while since my Venue Pro had seen the light of day...
When all was said and done the OS version on the Dell Windows Phone is 7.10.8773.98 and the firmware version is 2250.1800.7720.219. Because the process dealt with several updates, for me, the entire process ran about ninety minutes. If you have been using your Dell Venue Pro more regularly than I, the process may be shorter.
The Dell Venue Pro is a decent Windows Phone (still can't get used to the buttons) and it's nice to see the Venue Pro getting a little update attention.
Thanks, everyone, for the tip!
