Tethering your iPhone

How to tether your iPhone 3G, 3GS, 4 or 4S

You can use your iPhone to connect your computer to the internet by tethering (or linking) the two together. Once you've tethered your iPhone using a USB cable or Bluetooth, your computer will be able to download from the internet using your mobile phone conection.

To do this you'll need a tariff that lets you tether your iPhone. The cost of this extra service varies from network to network. You can find out more about adding tethering to your account and how much it costs by contacting your network directly.
