There have been a TON of questions about this monthly Premium Data charge. I hope this will clear things up.

If you buy the Sprint 4G EVO, you have to pay this $10 charge each month. This is specific to the device. It's not related to whether you are using 3G or 4G. It is required if you have the phone.

Because the phone has a faster processor, a huge 4.3 inch screen and an 8 megapixel camcorder/camera, we expect you will be using a lot more data than you would with our other devices. These features will give you capabilities that have previously never been available on a wireless device and we think they provide a premium experience. (Remember, this is the world's first 3G/4G Android phone.)

Separately, some have asked about the $29 a month hotspot charge. (You can connect up to 8 WiFi-enabled devices to one EVO if you pay that monthly charge -- but this is optional.)

I hope this clears things up. While some don't like it, even with these charges, we're still cheaper than AT&T and Verizon, who's 4G networks exist on some beautifully designed PowerPoint slides.

Makes sense to me.
