I have the unlimited data/tethering plans on my phone. Yesterday, I traded in my Rezound for a Nexus. I am able to tether every device I've tried to the phone and get internet except my Xbox. It just won't connect to the phone for some reason. I've checked and changed the password many times, and even tried the unsecured/no password mode. Nothing seems to work. I had no problems with the Rezound in this respect.
