Why do people jail break their iPods/iphones?

So I hear all this stuff about jail breaking iPods and iPhones and stuff. How do you do it? And what is the point… I'm confused.

They is loads of videos on you tube that show you how and it so you can download free apps like all the paid apps became free

When people jailbreak their iPods and iPhones, they get Cydia. Cydia is used to download cool features. Features that aren't available regularly on the idevice.

Watch youtube tutorials on it. I did it to my ipod because it offers amazing benefits! Apps are free, you can change the colors on the keyboard, you can have moving backgrounds, etc… But it also has it's downs. Your device becomes too open and can be hacked VERY easily. (unlike an un-jailbreaked device that has loads of protection) And sometimes it can actually crash the whole system, you're battery becomes drained faster, the device is much slower, and the apple store won't help you fix it if they find out it's jailbroken.
