AT&T Dell Venue Pro finally getting Mango update
Although just about everyone in the world has managed to get the Windows Phone 7.5 "Mango" update, there was one straggler left: the AT&T Dell Venue Pro (see review) While not a significant share of the Windows Phone market (the DVP was never sold directly by AT&T), it was still a black eye to those who own that phone, as one could argue that Mango greatly improves the Venue Pro (it breathed new life into ours, that's for sure).
The good news is that you should be able to plug in your DVP to Zune and fetch Mango right now to get your phone on the latest and greatest. Sure, you won't have the compass feature and tethering is uncertain, but the build of the OS is hopefully worth waiting for.
