Jailbreak или no jailbreak? :/

hmmm
I really want to jailbreak my сделать ставку, ipod touch which will give me access to apps that яблоко hasn't сказал(-а) ok to,full costomization options,and be able to install unsigned pirated software.

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

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