It's been a while, but Ryan Petrich's (@rpetrich) LiveClock jailbreak tweak is finally compatible with iOS 5.x.x-powered iDevices.

The iPad's great, but for some reason there are a few built-in iPhone apps Apple decided to keep away from the "magical and revolutionary" tablet. If you have an iPhone and iPad, you'll know that your smart phone's Calculator, Clock, Compass, Stocks, Weather and Voice Memos apps aren't built into the iPad version of Apple's mobile operating system, which is a bit of a shame (especially, I would say, with regards to the Clock app).
