We have heard recent complaints about the Dell Venue Pro not being able to connect to secure WIFI networks. The issue has not affected all handsets, and now an explanation has become available.
According to XDA-Dev poster dacunto Microsoft has admitted at its store that Dell had seen shipped out engineering models. The Microsoft store fixed the issue by swapping the Venue pro for a HTC HD7, without the WIFI problem of course.
Interestingly reader Justin, who sent us the Dell Venue Pro unboxing video, had noted that his battery was clearly labelled as an Engineering Sample, confirming to at least some degree that Dell is having problems with what is leaving its factories.
