Sprint's WiMAX-powered Evo 4G.

The Evo 4G weighs 170g and measures 120.5 mm by 67 mm by 13 mm – it's definitely a big phone, but it's still within the realm of reason. The phone runs Android 2.1 on a 1-GHz Qualcomm Snapdragon QSD8650 chipset, swapping 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 - yes, it has a front-facing camera. The camera also records 720p, high-def video, which it can play through an HDMI out jack on the bottom. Its 512 Mbytes of RAM is assisted by a MicroSD slot supporting up to 32GB cards; an 8-Gbyte flash card comes with the phone.
