What are the things I should not touch?

[Jerrryy]

Hi! I was wondering what were the folders and files I should not change or delete on my ipod? I know that I should never touch to springboard.app, but what about the other files? I have an iPod touch 4th gen running ios 4.2.1. Thanks!

Well, since your asking this question, it's best not to touch anything. Knowledge yourself with the filesystem and read around , then u could be ready. While your at it, don't touch a cactus or anything pointy

Fire hot. Don't touch. Why are you wanting to mess with your files/folders anyway?
