Before I move from my jailbroken 3.0 to jailbroken 4.0, I was hoping I could get the answers to a few questions. I currently have a jailbroken ipod touch 2g and have quite a few apps that have saved data on them, with routines and similar data. If I jailbreak, will I lose the data I have on those apps? Hopefully someone can help me with this, so I can make my final decision about going to 4.0. Thanks!
