Re-enable iPhone tethering with iOS 4
Posted in How-To on Jun 8th, 2010
The bad news is that you may lose your tethering option after updating to iOS 4 from your previous iPhone OS 3.1.3 installation. The good news is that my 3.1.3 solution still works with iOS 4, so just follow https://www.kaisblog.de/2010/02/19/reenable-iphone-tethering-313/ to re-enable tethering on iOS 4. Good luck.
