Ok, there's a few things I like about my Jailbroken Ipod touch, but for the most part I don't use the JB functions at all. So I was thinking of going back to being unjailbroken. Since there's a new firmware 3.1.3 out, will it be as simple as upgrading the firmware since it currently doesn't support the jailbreaking I did? Just don't want to lose game saves etc. or ruin my iPod touch for that matter. Oh, and will I regain the space from the jailbreak?
