This is going to probably be worlds stupidest question but I will receive Leopard tomorrow and am wondering if its ok to load my jailbreaked ipod onto it (as in none of the settings will mess up)
I don't think it's been discussed yet... so good job on asking, and I'd recommend waiting for a solid answer. You could also try running the jailbreak software without your iPod plugged in and see if it's running fine I guess.
But as long as iTunes isn't a different version, I'd think there'd be no issues.
