Through jailbreaking, you are able to add additional applications to your iDevice. It allows you to do so by adding an application called Cydia to your iDevice.

There’s actually two kinds of jailbreaks, one of them is a bootrom jailbreak which lasts for ever. That jailbreak like Geohot’s latest Limera1n jailbreak. Limera1n’s exploit is still being used up till now on all iOS devices except the iPad 2 and iPhone 4S (which are recently released after the release of Limera1n).
