The Apple iPhone is a popular smartphone with many useful features. One feature of the iPhone is that the device may be used as a tethered modem for a PC or laptop. Using the iPhone dock-connector-to-USB cable, the iPhone will serve as a dial-up modem for a computer. If the iPhone is using a 3G connection, calls may be made and received while the iPhone is enabled as a modem. To use the iPhone as a modem, the iPhone must be configured to act as modem. Next, a connection is created for the iPhone on the computer. Finally, the connection is made and tested. The iPhone has automated many of these functions, so using the device as a modem may be configured in just a few easy steps.
