It will.
Updating the iPod Touch software erases the jailbreak. You can update, but it will erase your jailbreak.
No because if u do it will erase your whole jailbreak.
no, to get a newer jailbreak you have to restore the ipod touch and then update the ipod touch and then download the jailbreak. that is a huge con for jailbreaking.
Yes and no. If you sync it your iPod will remain jailbroken. If you update it to say 4.1 it will un-jailbreak your iPod. Then you will need to re-jailbreak it.
Yes, first sync your ipod though. Don't update to 4.3.4 or 4.3.5 yet as those have no untethered jailbreak.
Simple answer: Yes.Only update when the Jailbreak you use has a new version / then only update the Jailbreak, not the iPod/iPhone.
Either restor or update it but you will loose averthing on it including jailbreak
It does not, unless the update is interrupted or, you restore instead of update.
if its already jailbroken than you will need to unjailbreak it (take the jailbreak off) then when its normal ;go to itunes go to and click update and cancel it because it will erase every thing than push shift+restore and it will update .then when its done install your jailbreak program:blackra1n,redsn0w,etc.
Not without erasing the jailbreak.
It tries to prevent hacking with jailbreak.
No you just update form iTunes
