I've been using the Internet Tethering option on my iPhone 4 ever since I've had it. It's a great way to connect to the Internet if there's no WiFi in sight, however, after updating to the 4.1 firmware from Apple, I connected to the internet via bluetooth tethering and then the option in settings just went missing.
Before, on my iPhone 3G, what I did was just reset the network settings, restart my phone, and it appeared but that doesn't seem to be the case. I tried to search Google but all I found was for the old 3G and 3GS instructions. Well, I stumbled upon this by accident and it seems that you need to enter a separate APN for Internet Tethering under the network settings menu. Maybe this is a new option for the 4.1 firmware.
After that, the Internet Tethering option in settings magically appeared. So for those of you having a hard time finding the internet tethering option for your iPhone 4, hope this helps.
