If you need to update an old ipod but don’t have or want to subscribe to an itunes account we have a website for that. Follow the link below to download the firmware restore files you need. I have a very old g2 ipod touch and really wanted to update the browser more than anything but found i couldn’t as apple required me to sign up for an account to do this (which also requires a credit / debit card) … the link below solved all my problems.
