The first man talks on restoration an iPhone (iPhone erases all its contents). You can also restore from iTunes. Connect iPhone to your computer and open iTunes. Click the Reset button on the screen showing iTunes settings of your iPhone. To reset / Reset the iPhone, one way is to hold down the Start button and lock button until Apple logo appears. The iPhone is restarted. You can also restore your iPhone from the same place that you can restore in iTunes.
