Jailbreak または no jailbreak? :/

hmmm
I really want to jailbreak my ipodの, ipod touch which will give me access to apps that 林檎, アップル hasn't 発言しました ok to,full costomization options,and be able to install unsigned pirated software.

but...
the downside is that it isnt completely ok..
林檎, アップル doesn't let us do things like this for a reason.
once あなた jailbreak your device its open to malware and viruses,it can become a bricked device (where あなた are forever unable to use it)i could loose my warranty,and new アップデート won't get to me very quickly...

I just want to know..do あなた think it's worth it?
