I jailbroke the day that the 3.0 JB came out. I've run on that same JB up until now. However, I'm sick of categories, and some of the other JB things I've installed. Something has broken various features (Namely forcequitting apps - leaving both Safari and Mail running at all times). Now, should I just restore? Will re-jailbreaking (pretty much just for a few apps/tweaks) cause force-quit to stop working again?
