I can't seem to get MyWi working for USB tethering. The WiFi tethering works great. I have the latest version of MyWi and 4.1. and the latest version of iTunes. I wish there was even a step by step process on how to set up USB.. but there isn't. Anybody know of a solution? On my iPhone 3G (running iOS 3) it worked.. but not on my iPhone 4. thanks!
