no sadly you cannot jailbreak ipod nano's you can only jailbreak ipod touch, iphone, and ipad.
No, because it will just get rid of the jailbreak. Plus, there isn't another jailbreak yet for iOS 6 anyways, so i wouldn't if i were you.
Not without erasing the jailbreak.
I tries 10 times but my iPod didn't jailbreak after restoring it :(
yes, since it is already jail-broken it wont run the risk of being bricked or broken. i am doing this right now and my ipod is completely fine.
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 but you will lose all the jailbreak features.
You get Cydia, a jailbreak software sometimes it comes pre-installed iphone. Sometimes your ipod wont turn on, and Will be a little slow a few times but it is worth it to get it jailbroken and get apps for free rather then paying 6.99 for one app.
You get sydia
i really dont think there is but i might be wrong. I made a mistake about downloading the 4.0 because i hade a my ipod jailbroken for the 3.1.3 firmware.so if you have 3.1.3 you can jailbreak your ipod so dont upgrade if you want to jailbreak your ipod.
You probably updated your iPod and therefore causing your jailbreak to go bye bye.
you download iLiberty+ from theiphoneproject site and connect the iPod to the computer. If the selection "Jailbreak" is grayed out, then it is.
