So I've been thinking about jailbreaking my iPod touch lately and I already know most of the pros. The things I'm worried about are the cons. Can somebody list all the cons for jailbreaking on 3.1 firmware? I have a 2nd generation touch. Also, how do you avoid getting bricked? What causes a brick? Lastly, how many times do you have to restore throughout the process of jailbreaking and un-jailing back to stock? Thanks in advance- Joey P.S. If anyone wants to give any opinions as to if they think jailbreaking is too risky or anything. I use my touch A LOT and I don't want it to become unusable. Since jailbreaking voids the warranty, once you restore back to stock can Apple tell you jailbroke?
