Internet Tethering

Just had a question from Jason Murray who asked why Internet Tethering (using the iPhone as a modem on a laptop) didn't work anymore, and hadn't since an operating system update a few days ago.

The answer is that it's still very much available, but the option is now called a Personal Hotspot, and when you turn this option on, it not only connects to the internet, but lets several devices share the connection. It's a nice new feature and if you have upgraded your iPhone to OS 4.3 you find it under Settings, as in the picture below, and you just need to select the Personal Hotspot option and turn it on. It supports both USB and Bluetooth connections.

Another thing to check in some areas is your data roaming settings.
