I recently updated my 2.0.1 JB to the "improved" 2.0.2. I wouldn't be surprised if we see a lot of updates to counter JB's as an attempt to increase App Store sales. Anyway, I decided to JB 2.0.2 with Quickpwn, and it seemed to work well. None of my Apps that I loaded via SSH/SCP were there, so I began to gather them up to transfer to my ipod. I was confused as to why my free space had not changed. The "Application" shortcut to /private/var/stash/Applications.blahblah (where you drag .APP folders) to my surprise showed all my old custom apps! I was curious as to why they were not loading, so I did a little investigating inside my file system. I discovered that my /private/var/stash/ directory was filled with duplicate folders of everything (fonts, apps, themes, etc.). They each have a unique 6 letter/number designation, and when I updated to 2.0.2 and did the JB, it changed all of those designations. Long story short, if you take the same route I chose, be sure to free up that wasted space. Its quite easy to transfer what you want, and then delete everything else. Hope that helps!
