As used to access the diagnostic menu and unofficially tether your Samsung Windows Phone 7 devices, the dialer code ##634# is used. On the Dell Venue Pro, however, something interesting happens. WMPoweruser tipster Richard states:

Saw the article about tethering the Samsung Focus…made me try ##634# on my Dell Venue Pro, which instead displays a Matrix screen…interesting Easter Egg.

This probably makes that code universal for all Windows Phone 7 devices, so keep it handy. In the meantime, you'll need to find the blue pill to get to the diagnostics screen.
