    The iPhone has many capabilities, one of which is tethering. When you use the iPhone as a modem to connect to the internet, it is referred to as iPhone tethering. This can only be done with iPhone 3G and up phones. What actually happens is that you use your iPhone as a modem that connects your computer to the Internet. Mobile tethering uses your iPhone data network that allows your computer to browse the Internet, when it’s connected to the phone. This is a great way to connect to the internet in areas where there is no Wi-Fi or for those times when you would like to surf on a bigger screen.

    iPhone as a Wireless Internet Modem

    • Unfortunately, for this method you’ll need to jailbreak your iPhone. Use Pwnage or QuickPwn tool to jailbreak your iPhone. Follow the instructions and run one of these software apps.
    • It’s also recommended that you install Addition’s iPhone Modem 2 software on your iPhone.
    • Once jailbroken, open Cydia. Now search for Addition’s iPhone modem 2 and install it. Next download and install ‘helper app’ on your computer.
    • Run the helper app and press connect. The helper app sets up an ad hoc wireless connection that can be accessed by an iPhone.
    • It creates a default network usually by the name of ‘iPhone modem’, which does not require any password.
    • Now open ‘Setting’ on your iPhone. Tap on the ‘Wi-Fi’ icon and turn it on.
    • Select the ‘iPhone modem’ network. As you open the modem iPhone app, everything starts configuring automatically. After sometime the iPhone app and the helper app will confirm that the wireless Internet connection has been established. Now launch the web browser and access the Internet from your computer.
