Some wireless carriers do not allow their customers to "tether" their devices for 3G access on a laptop. If you have an iPhone 4 and want to be able to tether it to your laptop in a public place where you do not have access to Wi-Fi, you may be confused as to how to do so. However, there is a way to enable tethering by way of Cydia, which is available from any jailbreak program. "Jailbreaking" your iPhone is necessary if you are interested in downloading apps from sources other than Apple.

    Connect your iPhone 4 to your computer with its USB cable. Install the jailbreak program to your device.

    Launch Cydia on your iPhone. The icon will appear on the display screen after the install is complete. Scroll through the choices until you see one that is called "TetherMe." Cydia offers the app for free in its package. Select the app and press the "Install" button to install it on your iPhone 4.

    Reboot your iPhone when the install of TetherMe is complete. Go to "Settings," "General" and "Network." Choose "enable" or "Install the Tethering Toggle for SBSettings." You will then be able to connect to the Internet by tethering your iPhone 4 to your laptop.
