Sprint's YouTube channel just uploaded a comparison video of the only 4G phones on the cell phone market today: Samsung's Epic 4G and HTC's Evo 4G. Sprint employee Heather walks us through a few features of the phones, mostly showcasing the Epic's 4-inch Super AMOLED display, QWERTY keyboard, and reminds us via the small print that "the Samsung media hub will be available post-launch." The clip also shows off the Epic's ability to connect wirelessly to your DLNA certified TV. Poor Evo ... he can only do HDMI out. Sprint's epic video -- pun intended -- is available after the break.
