Follow these simple steps to use your iPhone as a broadband modem when you laptop is not within range of a wireless network. Warning, this is a bit technical :-)

First of all you have to Jailbreak your iPhone and install OpenSSH via Cydia. I won't go through how to do that. You can go to http://www.quickpwn.com to download QuickPWN and jailbreak your iPhone. Once the phone is jailbroken, use Cydia to install OpenSSH.

The next think you will need to do is to create an ad-hoc wireless connection between your PC and iPhone. Once the ad-hoc connection is established, write down the IP address if your iPhone.

Using your favorite ssh client, execute the following command from your PC

ssh -ND 5555 root@IPHONE_IP_ADDRESS

You can use Putty to accomplish the same by clicking on SSH->Tunnels and then type 5555 in the Source Port box and clicking the Dynamic button. This will create an encrypted SOCKS Proxy tunnel between your PC and your iPhone. The last thing you need to do is to change your browser proxy settings on your PC to point to 127.0.0.1:5555

A few words of advise:

1. The AT&T data plan specifies “... Furthermore, plans(unless specifically designated for tethering usage) cannot be used for any applications that tether the device (through use of, including without limitation, connection kits, other phone/PDA-to computer accessories, Bluetooth® or any other wireless technology) to Personal Computers (including without limitation, laptops), or other equipment for any purpose. Accordingly, AT&T reserves the right to (i) deny, disconnect, modify and/or terminate Service, without notice, to anyone it believes is using the Service in any manner prohibited or whose usage adversely impacts its wireless network ...”

2. Some browser such as Firefox, do not send DNS requests over SOCKS even if the browser proxy settings are set to use a SOCKS Proxy. In Firefox, you can fix this by going to about:config and changing network.proxy.socks_remote_dns to true

Happy surfing! Some report getting 2500Kbps down and 250Kbps up on the 3G network!
