Amazon has just posted a good deal on the HTC EVO Design 4G, the $100 4G phone from Sprint that takes a lot of cues from its big brother EVO 3D. They are asking for just $30 for the device. It’s not bad for a 4 inch qHD phone with a 1GHz processor and 4G radios inside. You also have Android 2.3 with HTC Sense on top. Take a look over at Amazon Wireless.
