Talk about frustrating: when you’re in an area with decent coverage, the iPhone 3G can notch up some impressive documents speeds.  AT&T, though, won’t let you take advantage of all that speedy info by tethering the handset to your laptop; you’re only meant to use the unlimited plan on the iPhone 3G itself.  Of course, we know that being told “no, you can’t” only encourages some humans, and thankfully one of those society is Nate True.

Nate has figured out precisely how you can hook up the iPhone 3G to your laptop and use it as a tethered details modem.  He’s even put together a guide explaining all the different software you’ll need to take advantage of to do it.  The end aftereffect is a Jailbroken handset that can connect by WiFi to your computer, meaning that is actually wireless tethering.

Here’s the basic rundown:
- Jailbreak your

iPhone 3G
- Install 3Proxy and Terminal
- Create an ad-hoc Wi-fi network using your laptop
- Join the network with your iPhone
- Find the iPhone’s IP address
- Open Terminal and run the proxy program
- Open Safari on your iPhone and open a web page
- Configure your browser to use the proxy

Of course, doing so contravenes AT&T’s details plan terms & conditions, and as such could get you into trouble with the carrier.  And trouble in that case could mean a big fee for whatever tethered input you consume, or your contract being cancelled altogether.  Nate suggests you only use the method when in dire need; personally, I’d wait until the iPhone 3G unlocking system is finally made available, and save tethering until you have a contract with another company that allows it.
