Finding a tethering app that works on the Rezound was a lot harder than I though it'd be. I am posting this here for my own future reference if nothing else. WiFi Tether for Root Users (Google Play) It is free Use the following settings: - Device profile: Use "Generic ICS/Samsung Galaxy Nexus (CDMA)" or "Rezound (CDMA/GSM)" depending on if you have newest version or not. - Setup Method: Use "Auto" or "Netd (Master)" - Make sure the "Routing Fix" is enabled. It is a check box. On my ICS 4.03 Rezound it is very quick to connect.
