And, to be fair, when you do the math, the fees seem a lot more reasonable. A user will get unlimited voice and data on the 3G network, unlimited data on the 4G network, and the ability to connect up to eight Wi-Fi devices, such as laptops, gaming devices and digital cameras, to the phone—for $110 a month. Sold separately, those plans could total $130 a month. If users elect not to have the ability to turn the phone into a mobile hotspot, the rate drops to $80 a month. At $80 a month, Sprint is charging $10 more than any other voice and data plan. That’s because they expect you to use so much data on this device, they just had to do it, a spokesman explained.

The EVO was officially announced at a splashy unveiling at CTIA in March, but the pricing plans were kept under tight wraps until tonight at a New York City event (where they were showing Walt Disney (NYSE: DIS) Pictures’ Prince of Persia: the Sands of Time before its Memorial Day release).

As a refresher, this phone has a very large 4.3 inch touchscreen, is thin, and runs Google’s Android operating system. It has two cameras, an 8 megapixel auto-focus camera with HD-capable video camcorder and a forward-facing 1.3 megapixel camera. The device can easily be plugged into a HDTV to play video on a fullscreen. But those are just some of the hardware specs, the phone will come with a new video chat service from Qik, and will allow users to upload HD video directly to Facebook, YouTube or Twitter.

The big caveat with this device is that it will only get 4G speeds (which can be up to 10 times faster than 3G) in the 32 markets where Sprint’s partner Clearwire (NSDQ: CLWR) has built a network. More markets will go live in the remainder of 2010.

Earlier today, a Sprint executive told Reuters that a long waiting list had already formed of customers wanting to buy the phone. Whether those people remain interested in the product now that they actually know how much it costs, we’ll have to wait and see.
