Tethering is a feature of the iPhone that allows you to use the phone as a modem when connected to a computer. Although iPhone users using AT&T currently cannot tether their phone to the computer, other carriers allow this feature by providing an additional plan for phone tethering. To avoid unexpected charges to your phone bill, call your phone carrier and ask if you are able to tether the device to your computer.
