How to stop a iOS 6 download?

I'm currently trying to download an update for my iPhone 4s. It's the iOS 6 but it seems to have stopped and it says estimating time remaining… And I was wondering if there's any way to stop or reset it?

Hold down the power and center button at the same time for several seconds to restart the iPhone

I believe the cancel button would work in android it commonly being used

Is it the same with ipod
