How To Tether Your iPhone 3G For Browsing The Web Via Laptop

Now that there is an iPhone that runs on the much faster 3G networks, one of the things we want to do with it is naturally plug it into our laptop and use it as a modem when Wi-Fi isn’t around. After all, we’re paying for “unlimited” 3G data, right? Well if you’re one of those people, you’re in luck. Nate True has put together a method for tethering your iPhone 3G to a laptop for use as a 3G modem has been found.

  7. Open Terminal (on your iPhone) and run ‘socks’ (no quotes)
  8. Open Safari on your iPhone and load a web page
  9. Configure your browser/computer to use the socks proxy on your iPhone
