Well, we have a great tweak for you that will give your power icons buttons on your SprinBoard. It`s called “PowerIcons†and it allows you to reboot, respring, go into safe mode and shut down by just tapping an icon. It`s without a doubt quicker than the usual holding down of the power button for a few seconds before sliding to power off.
This widget is available for free on Cydia, under the BigBoss repo and of course you`ll need a jailbroken iOS 5.
