I just spend $20 and bought the Mywi license from Cydia, and the Wifi tethering is not working. Every time I turned it on, it will wait for a while, then shows "Cleaning off Mywi, please wait....", then it turned off itself. Any one experience similar problem? this is on an iphone 3gs with tethered jailbroken iOS 5.0.1. The USB tethering works fine.
