As you are all aware by now, Apple has released the 3.0 firmware for the iPhone 3G & and the newly release iPhone 3Gs for free. iTouch users and 2G people have to pay for the update. Lots of exciting new features are added which you can see all the updates at apple.com.
Here I would like to show you how to enable tethering for free on your iPhone or iTouch. It is extremely easy, I will late out all the directions and just follow accordingly.
From you iPhone or iTouch navigate (meaning go) to this site:
1. You will see the following page. Click on your provider, generally AT&T
because 3.0 has not been jailbroken as of now.
2. Tap on the install button.
3. Tap on the install now button.
4. Tap on the done button.
5. Finally, go to Settings -> General -> Network -> Internet Tethering and tap on the toggle button to enable tethering.
6. And select either the Bluetooth method or the USB method. I prefer the USB method because you get to charge your iphone as the same time. So there you go, any questions drop a comment and I will get back to you.
