I tried to activate wifi theathering and of course it warned me that I needed to have this set up for my account. Sprint's rates are pretty pricey. I haven't rooted yet, but noticed there was also bluetooth tethering. I pressed on that but didn't have BT-capable device to try it out with, but it never prompted me to sign up with Sprint, so I was just wondering if anyone had gotten that to work? Anyone using another app without rooting to tether?
