Make sure that you are using the correct jailbreaking tool for your iOS version. For example, if you have the iTouch 5th generation, with iOS 8.1.2, you would need to use TaiG to jailbreak.
its not 100% safe and still has a chance of breaking. Remember if you do jailbreak you itouch and it breaks your warrantee will cancel out and you wont be able to buy i new one unless you buy a new one. And you can jailbreak your itouch from either jailbreakme.com on your itouch or ziphone.org on your PC
it will let you get free apps but if it breaks they don't give you a new one
you cannot multitask on the itouch unless you jailbreak it.
no it wont have your features
That is actually impossible. Jailbreak is only for iPad, Iphone, and Itouch.
Updating the iPod Touch software erases the jailbreak. You can update, but it will erase your jailbreak.
