The phone runs Android 2.1 on a 1-GHz Qualcomm Snapdragon QSD8650 chipset along with a helpful 1GB of built-in memory and 512MB of RAM, which is assisted by a MicroSD slot supporting up to 32GB cards. It swaps between EVDO Rev. A, WiMAX and Wi-Fi 802.11 b/g on demand. The phone is dominated by a 4.3-inch, 800-by-480 65,000-color TFT LCD capacitive touch screen. There's an 8-megapixel camera on the back and a 1.3-megapixel unit on the front. The camera also records 720p, high-def video, which it can play through an HDMI out jack on the bottom. The Evo 4G weighs 170g and measures 120.5 mm by 67 mm by 13 mm. It's expected to hit the market in the summer."
