Got the blue tethering screen on Mac & iPhone, but no internet. What am I doing wrong or did I miss a step? Thanks in advance!

These are the steps I took.

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

1. Download this file (for AT&T) and mount the disk image (thanks Gizmodo) for other carriers, try here.
2. Option-click on "restore" in your iTunes with your iPhone attached. Browse to the opened disk image file and hit OK. It will update phone settings for a few seconds.
3. You have tethering. Now go into your iPhone/settings/general/network/Internet Tethering and turn it on.
Boom - 3 steps to tethering...

I've rebooted the phone & the Mac. No luck!
