With its backlit keys and shaved corners, it could only be the Droid 4 leading the pack of phones in this Best Buy promo shot. The slider hasn't yet reached the shop floor, but that hasn't stopped it from promoting the big box retailer's Rewards Zone offers. While Verizon has already let a festively-colored Droid RAZR and a pair of Xoom 2 Xyboard tablets out of the gates this winter, keyboard hunters have been left out in the cold. Hopefully, this snafu will translate into a release very soon.
