I rooted my HTC EVO 4G and I installed the Wifi tether for root users app. But when I tried my ipod touch it shows my phone as available it like the wifi shuts off on my ipod touch, so I tried it on my laptop it shows connected with limitations and I notice a lot of people were doing it on 2.1 but I'm doing it on 2.2. Did they (sprint) do something to block it ?
