With the release of firmware 3.1.3 the tethering option is back on the iPhone. After the reboot of the iPhone you get additional fields in the 'Cellular Data Network' section in the 'Network' menu (Settings -> General -> Network -> Cellular Data Network). Just enter the appropriate information in the APN field (for KPN in the Netherlands enter internet in the APN field) and the Internet Tethering option is back (w00t) in the 'Network' menu.

iPhone Firmware Update 3.1.3
Apple released an update for the iPhone. Release 3.1.3 fixes some issues like;
- improves accuracy of reported battery level on iPhone 3GS
- resolves issue where 3rd party apps would not launch in some instances
- fixes bug that may cause an app to crash when using the Japanese Kana keyboard
- Tethering is back (even on the non exclusive carriers)....
Results may vary since not every carrier allows tethering (like T-Mobile in the Netherlands).
