The other day, my iPhone locked up and just displayed this dim screen with a wait cursor, an alert that I had missed a call and the regular background. I tried to get it to get out of that state using the regular means but it was stuck. It was really frozen! Fortunately, this was the first time it happened but unfortunately I didn’t know what to do. Then I remembered how rebooting an iPod works and tried to map it to the iPhone controls. Here’s what to do to reboot your iPhone:
1. Hold down the Home button (that’s the big button in the lower front) and the Sleep / Wake button (that’s the little button on the top right) down.
2. Keep holding until you see the screen go black and then the Apple logo appear.
3. Voila! Your iPhone has been rebooted. Resume your blissful life and forget that anything bad happened with your iPhone.
