A few years ago, manufacturers started introducing webtop capabilities to smartphones, and this device was one of the best examples. At the time of its arrival, media praised it for its design, display and ability to spar with Samsung’s Galaxy S II. Made by a company that developed what I consider to be the best Android handset this year, the device landed on Sprint and featured blazing quick WiMAX and global phone support.

What you’ll notice about the device is that it featured a unique design with cutoff corners, instead of the typical rounded edges. It’s a design we’ve actually seen used in a lot of this company’s devices, which is a pretty big hint at what we’re dealing with here. Taking that into account, plus some hints in the pictures, and I’m sure you’ll put two and two together relatively quickly. If anything, it’ll rule a lot of companies out.

The device itself has a 4.3-inch display, removable back, and a nice little kickstand on the rear, though it was super tough to actually flip it out. One of the neat things about the kickstand was that it could actually open an app once it was deployed, adding a bit of extra functionality. The device is pretty thick, though for its time it was among the average, and it’s really darn heavy compared to what’s around today. Under the hood was a 1650mAh battery, 8-megapixel camera, 16GB of internal storage and Tegra 2 processor.

This company today doesn’t quite have the reputation it didn’t years ago, but it’s made some cool devices throughout the years. This mystery device is definitely among some of its stronger efforts, and offered a lot on a carrier that was quickly falling behind. With a cool design, webtop functionality and a nice little kickstand, it definitely stood out. So have you guessed it yet?
