There are so many tutorials and videos out there that teach how to jailbreak ipod touch and iphones but the techniques have improved way too much and here is the easiest way which is just a matter of two clicks to get your iPhone or iPod touch jailbroken. If you are not sure what jailbreaking is then go to the wikipedia page to know more about it.
Why would anyone want to jailbreak his device?
There are a number of reasons. Jailbreaking is similar to rooting your android phones. Jailbreaking gives you much more control over your device. For example, iOS does not by default allow you to change the wallpaper or the theme. But jailbroken devices do.
Here are the assumptions that I've made -
You have a iPod touch or an iPhone running firmware 3.1.2.
Steps follow -
1. Download Blackra1n for your firmware from here - http://blackra1n.org/download-blackra1n/
2. Start the blackra1n.exe
3. Your device will be automatically detected. Just click on the only button that blackra1n.exe provides. Wait for a few minutes and your device will reboot.
4. When your device reboots, you will find a new icon called blackra1n in your device. Open it. Connect to the internet. Download 'Cydia' Installer. Once you're done there will be another icon on your device called 'Cydia'. Using this installer, you get to download lot many applications to your iphone!
This is how you jailbreak a iPod touch or iPhone :) Hope that helps.
PS: There are other ways of jailbreaking a device. This method involves using blackra1n. There are other jailbreaking agents like redsnow, snowbreeze etc. But I personally like blackra1n for its simplicity.
