iPhone crash Re-set

I have one of the first round of iPhones. It crashes more than others I've seen. The iPhone is stable, but it still occasionally crashes. These tips may come in handy if you have similar issues:

To force a program to quit: Press and hold the Home button for six seconds to force-quit a program that seems to be "stuck."

To activate a hard reset of the iPhone: Press and hold both the Home button and the Sleep/Wake switch for eight to ten seconds. You’ll see the screen go black, and then the Apple logo appears as the iPhone reboots. Sometimes, I've just had to re-install the software.
