Dell’s Venue Pro smartphone had its share of setbacks at launch, but we really grew to enjoy the device once the wrinkles were all ironed out. The build is outstanding, the design is sleek, the slightly curved display is unique, the 4.1-inch AMOLED display is nice and vivid, and we have big hopes for Microsoft’s Windows Phone 7 platform. On Thursday, Dell quietly launched a new version of its Venue Pro smartphone, this time with T-Mobile’s 3G bands swapped out for AT&T’s. Beyond that, the device has the same great look and feel, the same great build, and the same affordable price tag — just $99.99 with a 2-year contract.
