iPhone 3.0 is live! so I am going to post 9to5mac.com’s tethering tutorial for you guys, or you can go and support them on their site.

You now don’t have to do any downgrading or torrenting. Seems you can just run a little command in terminal (Make sure you are on OS 3.0 on a 3G iPhone and iTunes 8.2):

On a Mac:

Open terminal and paste in:

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

Hit enter, it’ll look like nothing happened… but it put iTunes into a testing mode that lets the rest work.

After that, the steps become a lot more simple.

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… [via 9to5mac.com]

Or if your on a PC:

C:\Program Files\iTunes\iTunes.exe /setPrefInt carrier-testing 1

For people who are unaware of what tethering is, it’s using the iPhone’s EDGE or 3G connection and using it on a computer which the phone is either attached over USB or Bluetooth, sharing the connection so that if you have no WiFi and you don’t have a 3G card you could just plug in your iPhone and browse away.
