I am thinking to jail break my ipod touch 4G though snowbreeze ?

If u use any thing use jailbreakme.com that way you won't lose anything and when it boots it takes forever and if you download anywrong thing your iPod will have to be restored like mine did so I just gave up I have never heard of snowbreeze so that's like new to me jailbreakme.com jailbreaks it right from your iPod in mobile safarie but u have to have 4.0 or lower firmware
