Frozen or Unresponsive iPhone

This can often fix a few issues:

1. Memory clogs
2. Unresponsive phone
3. General odd behaviour
4. Slowdown

If a normal shutdown won't fix the problem, you can try a forced reset.

Press and hold the Sleep/Wake button and the Home button at the same time for at least 10 seconds, until the Apple logo appears.



And there you go.
