How to Activate iPhone Tethering With Firmware 3.1.2 (3G and 3GS)

Now that Geohot has released the blackra1n RC3 jailbreaking tool, activating tethering on an iPhone 3G or 3GS is a snap. Many international users already have tethering, meaning they can share their iPhone data connection with a computer. AT&T does not offer this option in the US.

Fortunately it's never been simpler to tether if your iPhone is running the latest firmware (3.1.2). Follow these steps to activate tethering, just keep in mind you are breaking all kinds of agreements with AT&T and Apple in the process.

The latest version of the blackra1n jailbreak has hit the streets. RC2 will even jailbreak brand new iPhone 3GS models running 3.1.2 from the factory with a "tethered jailbreak."

This means when restarting your jailbroken iPhone the device must remain connected to your computer to properly boot. Apple thwarted the “24kpwn” exploit used by Geohot and iPhone Dev-Team in the latest firmware release on new iPhone 3GS models, making the tethered jailbreak method necessary.
