I have a friend who has an Atrix 2, which I recently helped him root. It's running ICS. He tried Foxfi for wifi tether, which works (side loaded, since AT&T blocks it ) but has the time limit. He was reading reviews about the paid version of Foxfi that it didn't work (not sure if he saw if it was specific to this phone or others). So my question is - what's a reliable (and unlimited) wifi tether app that can be used on a rooted Atrix 2 running ICS? Thanks in advance!
