I just rooted my Evo 4g so that I can use Wifi tether for my iPad. I'm fairly new at all this rooting stuff. Does the rooting and wifi tether violate Sprint's Terms of Service? I've read that it does and some say that it doesn't. I know that rooting voids the warranty, which I don't mind, but I'm more worried about the wifi tethering. And also how would Sprint find out?
