If you're internet goes down, then utilising your smartphone's 3G connection by connecting handset to your PC (a process known as tethering) is a great way to get back online.
Use your Apple smartphone to get your PC online
Previously, the only way to 'tether' an Apple iPhone was by jailbreaking it – a move that many consumers just didn't want to make. However, with the introduction of iOS 4, came the functionality. Here's how to turn the function on.
It's worth remembering to check your network's terms and conditions on tethering and keep an eye on your data allowance as depending on your web activities you could find yourself hitting your mobile data cap a lot quicker than you think. Exceeding your data limit may result in an unwanted charge. Here's how to tether an Apple iPhone.
From the Home screen select settings.
Press General and then select Network.
Now press Internet tethering to turn the function on.
You can either connect your handset to your PC by the USB cable it came bundled with or by Bluetooth.
Once the handset is connected to your PC, select the iPhone from the list of connections available using the Internet access icon in the system tray. Press connect and you'll be able to surf the web using the handset's 3G connection till your heart's content.
