Since iOS 5 hits tomorrow, jailbreak developers are starting to update more of their widgets, tweaks and apps to be compatible with Apple’s latest and greatest iOS firmware.

Along with that, we here at iDB have begun to take a keen notice of what’s available for jailbreakers. Many of the current jailbreak tweaks for iOS 5 are Notification Center widgets, and few are prettier than PowerCenter.

PowerCenter is a tweak that allows you to quickly respring, reboot, or power down your iPhone with a slide of your finger, and it’s a beauty. Catch the full video walkthrough after the break…

As you can see, PowerCenter is simple — you can perform the same actions easily with SBSettings, or various other tweaks — but it’s the gorgeous design of the widget that really grabbed my attention.

PowerCenter is a perfect complement to the linen background that graces Notification Center, and it works without any of the problems that plague some of the other beta widgets available thus far.

If you want to give PowerCenter a try, add the BigBoss beta repo to your list of Cydia sources:
