You remember the Samsung Galaxy S Pro that we showcased here a few weeks ago, right? Thanks to our tipster, we got early photos of what would later become known as the Samsung Epic 4G -- and that's exactly what we've got here, courtesy of an official announcement from Sprint and Samsung. It's the first 4G-enabled device on the market that features a full, landscape-sliding QWERTY keyboard, and it's also got a few more features that'll make you take a second glance.
