This additional charge will be mandatory for all HTC EVO users, regardless of whether they live in a WiMAX coverage area or not, but it will give them true unlimited data instead of the 5GB limit on regular plans. The so-called 4G service sees average downloads of 6Mbps and is available in 32 cities in the US -- Sprint intends to cover 80 major markets by the end of 2010. Where WiMAX connectivity isn't available, the smartphone will fall back to Sprint's EV-DO network.
The HTC EVO has attracted a lot of attention with its high-end feature set, which includes a large 4.3-inch screen, 1Ghz Snapdragon processor, 512MB of RAM, and two cameras (an 8-megapixel flash-equipped camera capable of 720p video and a 1.3-megapixel front facing camera for video conferencing). It also includes the ability to share the WiMAX connection with up to eight other devices via Wi-Fi, but unfortunately Sprint will charge an extra $30 for this.
