Just done two ipods for the kids,
Updated them to firmware version 6.1.2
Note 6.1.3 seems to have just become available today lol
so I don't know if that is supported yet so used the previous version.
Used Evasion 1.4 to jailbreak. (newer versions are available but I just used
the same versions that where posted in the tutorial)
Says it also works on Iphones and Ipads too.
but our Ipad is only a few days old so will let the kids
try it out on their Ipods first in case there is a problem.
Also tells you to back up what u have before doing it, and it is safe
to restore back to where it was initially if you have any problems.
Oh finally, it's also an untethered jailbreak.
