Many people use the Internet all the time now, but sometimes there's no Wi-Fi or Ethernet receptacles available. Tethering to a cell phone can be a huge convenience then. If you need to get online, your iPhone is one way to connect your laptop to the Internet. As of January 31, 2011, the iPhone is only available for AT&T customers, but when Verizon begins to offer the iPhone in February 2011, tethering will also be available for customers with qualifying plans.
Turn on Tethering
Tap "Settings" from the home screen of your iPhone.
Tap "General," then "Network," then "Internet Tethering."
Touch the "Internet Tethering" option to turn tethering on.
Press the "Home" button to go back to the home screen.
Tethering to a Mac
Connect your iPhone to your Mac laptop.
Reset your computer if it prompts you to do so. Otherwise continue.
Click the "OK" button on the New Interface Detected window if it displays.
Click "Apply" on the Network window, which should display automatically.
Wait and keep an eye on your iPhone's home screen. You should see "Internet Tethering" at the top of the screen when the connection is finalized. Your Mac is now tethered to your iPhone.
Tethering to a PC
Connect your iPhone to your PC laptop.
Restart the laptop if it prompts you to do so. Otherwise continue.
Wait for your PC to communicate with your iPhone. You should see the network icon in the lower-right of your screen change to indicate that it is establishing a network connection.
Check your iPhone's home screen. You should see "Internet Tethering" at the top of the screen when the connection is finalized. Your PC laptop is now tethered to your iPhone.
- You should probably turn off Internet tethering on your iPhone whenever you're not using it. This keeps you from accidentally using data when you don't want to.
