[help] iPod touch update&jailbreak

[iSadist]

Hey guys
My iPod touch is 1G ipod 16Gb

my questions are this.
http://www.felixbruns.de/iPod/firmware/
will this link above be able to update my ipod to the new-est version ?

and will jail breaking cause probs?
and sideeffects.

yeah, it will update your firmware. and no, jailbreaking shouldn't harm your ipod unless you do something with it (i.e. installing too much junk you dont need).
jailbreaking it will allow you to customize your ipod, which is a nice feature :]
plus, you're able to just run the program within 30seconds

I think if you want to undo it...you have to restore your iPod. It should allow you to sync stuff, just like a non-jailbroken iPod.
