Well Sprint "does" allow us to use our phones to tether with and doesn't really bother us about it unless you don't have an unlimited data plan for your phone. So no extra charges there. Just search "tethering" with your phone and you'll come across a lot more in depth detail on how to do it with Sprint.

On the Evo it's quite different, it allows up to 8 devices to be tethered via wi fi. This will be an extra charge from $10-$20.. No one knows yet in less the information just came out. Probably won't be to long after it is released that someone(s) might root the device and allow us to tether for free!
