iPhone OS 3.0 Tethering with 3 (Hutchison) HK

Following the instructions in this fantastic tutorial, I successfully enabled Internet Tethering on my new iPhone 3G (OS 3.0 beta 2), with 3 (Hutchison) Hong Kong as my service provider.

You can download this file if you have access to the beta OS image and follow steps in the above tutorial to enable tethering for your 3 devices.

Also I found something interesting: not only you can tether your 3G connection, you can also tether the Wi-Fi connection with your computer, making your iPhone a handy wireless adapter (for older computers without one).

Note:
- I only tested this with my own iPhone and I am a 3 HK subscriber.
- The file provided is for testing and developing purpose ONLY.
- Enable tethering may or may not violate your contract with 3.
- The tethering feature may slow down your iPhone system and cause syncing problems.
- DO IT AT YOUR OWN RISK.
