a variation of this that i always do after i install an app or rearrange my icons would be to press & hold the home button till the app quits (installer/rsbt,customize) and returns to the springboard unrefreshed. that's when i reboot by pressing the sleep/power button. as expected, springboard is refreshed when powered on while still retaining the usage stats. there's an added step but it quits the running app properly before i reboot it. all new settings are saved while the app was still running anyway.
