While Dell gets (and deserves) much criticism for some aspects of the Dell Venue Pro, the unlocked version gets pretty decent update schedules. We were just told by reader Clifton Thomas that the DVP was getting 7740. Sure enough, we fired up our ol' trusty slider, plugged her in and 7740 was waiting for us. It does not, however, add tethering or fix the compass, so don't expect any surprises.
As previously noted, the 7740 OS update fixes an Exchange 2003 email and voicemail notification bug, alleviating two potentially large problems for people. The update is mostly dictated by OEMs (unlocked) and carriers at this point and US markets may be left out. It is unclear if AT&T branded Dell Venue Pros (who just received Mango) will be getting this update, let alone the T-Mobile version. If any of our readers are getting it on their branded DVPs, let us know in comments.
