A risky proposition

Yesterday the world was introduced to the wonderfulness that is the iPhone 3.0 software update. I know around my office nearly every geek in sight was hunched in front of his or her workstation furiously foaming at the mouth waiting for the update to finish downloading and install.

The update provides some wonderful new features (searching, cut and paste to name a few) with a few promised to be “on the horizon”. What it doesn’t offer, for those on AT&T anyways, is MMS and Tethering, two of the most sought after features. Two that SHOULD be there, but aren’t because AT&T seriously dropped the ball.

For those who are adventurous, it IS possible to enable tethering on the iPhone on AT&T. While I do vouch for these instructions working, I do not know what – if any – repercussions may come from following them. You do so at your own risk, and I will not be held accountable for YOUR actions.

Having said that – here’s how to enable it (if you’re using Mac OS X)

  • First, download This File to your desktop
  • Next, connect your iphone to your computer. If it syncs when you first connect it, wait until it finishes syncing.
  • Then, run the following in a terminal: defaults write com.apple.iTunes carrier-testing -bool TRUE
  • finally, go to the device summary for your iPhone within iTunes, while holding down the Option key, press “Restore”. in the window that opens locate the ipcc file you downloaded in the first step, select it and click ok.

NOTE: If for some reason the ipcc file is grayed out, re-run the command in the terminal. I had to run it twice for it to work.

Now, tethering is enabled on your phone, to turn it on go to Settings -> General -> Network, you’ll see a new option there to enable Tethering. Click that button and follow instructions.

There you have it – you can do what you want with this information, but you do it at your own risk :-)

Enjoy!

[Update]: my buddy Brian points out that if you download the file linked above, directly onto the iPhone, it goes into effect immediately. shaving off three steps.  Thanks Brian!
