Jailbreak is one of the best way to enjoy your full control over your iDevice. Apple has been trying to stop Jailbreak but has not been  successful yet. There are two type of jailbreaking.

1. Tethered Jailbreak

2. Untethered jailbreak

In Tethered jailbreak you are restricted not to let you iDevice (iPhone, iPod or iPad) to “switch off”. If you are using iPhone, iPodTouch or iPad that is Tethered Jailroken and the devices turns off then it will stuck on “Apple Logo” and you have no other way left. The only option left to you is just to attach your iDevice (iPhone, iPod or iPad) to computer and then switch it on using Redsn0w.

In Untethered Jailbreak you are free to use your iDevice (iPhone, iPod or iPad) the way you like to. You can switch off your iDevice (iPhone, iPod or iPad) any time you like to, your device will never stuck on “Apple Logo”.

I hope this guide was enough for you.
