Just a couple quick questions about upgrading the firmware... Reason why I haven't done it yet is because I believe you need to "un-jailbreak" your ipod? This would require me to backup like 8 app's and my themes etc... Should I upgrade my firmware? To update do I need to "un-jailbreak" my ipod? What is so good about 1.1.2? Will there be any issues with applications running on 1.1.1 if they were made on 1.1.2 (or visa versa)?
