How to enable internet tethering on firmware 3.1.2: step-by-step tutorial
Here's a little guide that allows you to enable tethering on the iPhone 3G and iPhone 3GS with firmware 3.1.2. A hack that changes the CommCenter is used. It eliminates the need for a digital signature.
Here is a step-by-step tutorial:
1. First start Cydia and search for "iphone-notes". Install this repository and return to the tab "Search".
2. Now look for "tethering 3G - 3.1.2" or "tethering 3GS - 3.1.2" depending on the model of your device and install the package.
3. Restart the iPhone and then connect to the site www.unlockit.co.nz directly on the iPhone to create a custom APN. Create and install the profile.
After you restart you should see the field "Tethering" in the Settings.
