Shutdown IPhone when an application hangs [closed]

Question

My application hangs. Pressing the home button doesn't return to the springboard anymore. Additionally pressing the power button for 10 seconds doesn't turn the iphone off at all.

Is there any way to force a shutdown?

Answer 1

1 - To 'Force Quit' an iPhone application, hold down the Home button for up to 5 seconds.

2 - To force a reset (in rare occassions when 1 does not work), hold down the Power and Home buttons together for 10 seconds.

(this is documented in a Apple Support article - http://support.apple.com/kb/HT1430)

Answer 2

To force shutdown the iPhone 3G, just press down the power button first, followed by the home button. Hold the 2 buttons down until your screen changes.

That's it... A simple, but undocumented solution. Oh well. So far my iPhone has crashed in a few ways and this worked all the time.
