Sprint on Wednesday showed off HTC's Evo 4G, the first 4G-equipped phone to hit the US market. The Android-based device is a clear competitor amongst the range of high-end smartphones such as the Droid, Nexus One, and iPhone. With a gigantic 4.3-inch display, the Evo upstaged Samsung's latest offering, the Galaxy S, which offers a 4-inch screen. Electronista at CTIA had a chance to take a closer look at the upcoming device.
