If you are doing this app for the free tether think twice. Myself and another member have both measured max wireless tether speeds at .4 down and .1 up. This is both 3 and 4G. My 4G was doing 3-4mbs down and 1 mbs up but when I turned on the wireless tether it dropped like a stone. ANother member is saying the same thing. I'm pretty pissed because I still had the original root with no update and the tether worked just fine. Now it looks like it's toast. Anyone else having the same issue?
