Corrupted software

It isn't often that Apple gives specific directions about how to fix your problem! Restoring the iPhone 4S will erase everything on it, so make sure everything on the iPhone 4S is stored elsewhere prior to restoring. To restore, connect your iPhone 4S to a computer with iTunes installed. Click "Restore" on the iPhone 4S summary page (click on your iPhone icon on the left menu to find this page). Follow the directions to restore. If your iPhone 4S displays the text "Please wait. Very Low Battery," leave it plugged in. This charges the iPhone 4S enough to be able to restore. If the iPhone 4S hangs on this screen for long periods of time, you may need a new battery.

Force restore mode

If your iPhone 4S is hanging with an Apple logo, or exhibiting some other software problem that prevents iTunes from recognizing it, you can force it into recovery/restore mode and then use iTunes to restore the software.
If the device is powered off, plug one end of your USB cable into the iPhone 4S and leave the other end disconnected. Press down on the Home button, and keep holding it down while you plug the USB cable into your computer. After 5-10 seconds, you should see a "Please Connect to iTunes" image on the iPhone 4S, and iTunes should prompt you to restore the software; follow the prompts and the instructions given above.
If the device is powered on, hold down both the power and home buttons until the device reboots and displays the "Connect to iTunes" image (generally, 5-15 seconds).
God bless you
