Easy iPhone Tethering for AT&T users

If your iPhone is running 3.0, it’s very easy to enable internet tethering on AT&T’s network with no ugly hacks. First you’ll need to download this carrier settings file from gizmodo.

Next, quit iTunes and enter the following command in terminal:

defaults write com.apple.iTunes carrier-testing -bool TRUE

Contrary to many articles, you don’t need to install a pre-release version of iTunes.

When you restart iTunes, connect your iPhone and you’ll be able to option-click the Restore button to choose the .ipcc file in that disk image. Rather than doing a full restore of your iPhone, it will simply update the carrier settings. If the update is successful, the Network page under general settings will show an Internet Tethering option.
