It appears that the process I mentioned in a previous blog post on how to enable tethering in iPhone OS 3.0 via a quick carrier settings file downloaded from a website is no longer able to be accomplished as the URL referenced to download the file is no longer valid.
However, I have found another way to enable tethering on an AT&T iPhone running OS 3.0 in the US using a Mac. I just followed this process and it works for me, though your own mileage may vary. I’ve tested this on a 3G and 3GS running OS 3.0, but I don’t see why it wouldn’t work on a 2G running OS 3.0. If you try this on a 2G, let us know how it works by leaving a comment!
- Download this carrier settings file from my public iDisk
- Fire up Terminal on your Mac and type (or copy/paste):
defaults write com.apple.iTunes carrier-testing -bool TRUE - Connect your iPhone to your Mac and fire up iTunes
- Option-Click the ‘Restore ‘ button and select the .ipcc file within the .dmg file
- Enjoy the new tethering option under ‘Settings -> General -> Network ‘
If the tethering option doesn’t show up for you immediately, just reboot your iPhone for good measure. It’s unfortunate that the easy web-download method is unavailable anymore, but fortunately this new process still works to enable the very handy tethering functionality.

Update: It appears the iPhone OS 3.1 Beta 2 disables the tethering capability, so keep this in mind if you plan to update your iPhone to 3.1.
