Problem with Personal Hotspot on iOS 5

Having a busy week since upgrading to the iPhone 4S I hadn’t thought to test everything I had before the upgrade. The most important things worked so it wasn’t a big deal. That was until yesterday when I tried to use Personal Hotspot with my iPad.

It was epic fail, the option was gone. I don’t just mean it was off in the options it didn’t exist in the options.

I called O2 and they were less than helpful. I gave up on them and hung up.

Later I figured I’d try a network reset, this did the trick. Everything is now working as expected.

To do a network reset open Settings > General > Reset then choose Reset Network Settings. The device will reboot and can take a few minutes to reconnect to the network. You will also need to re-associate your device with any wifi networks you had setup.
