Sprint's first 3G/WiMAX-compatible smartphone is not expected to ship until sometime this summer, but it looks like pre-orders are just around the corner. A screenshot leaked from The Shack's (formerly Radio Shack) internal website suggests pre-orders for the much-anticipated HTC EVO will start "later this month," and lists some of the specs we already know: 4.3-inch 480 x 800 TFT display, 1 GHz Snapdragon processor, 1.3 megapixel front-facing camera, rear-facing 8 megapixel camera with auto-focus and 720p HD video recording, and MicroSD support (up to 32GB).

Apple is widely expected to announce its 4th generation iPhone at its Worldwide Developer Conference next month, so any head start that Sprint and HTC can get should be beneficial. The device will run Android 2.1 and has built-in mobile hotspot functionality for up to 8 devices to share its speedy signal – though it's unclear if Sprint will charge extra for the tethering service or include it like Verizon does with its Palm line.

Pricing is still unknown, but one of the many rumors pegs the device at around $200 with a two-year contract. There's no word on how much the plans for this HTC smartphone will cost.
