I have heard the only way to restore your cydia apps is to use AptBackup but that it fails most of the time. Now that Rock is owned by Cydia shouldn't we have nice features that Rock had like the Package restore? It's slightly annoying having to update then go back into cydia, add all your sources, download all the packages and set everything back up and it just seems like there should be an easier way...Granted if I were a developer I would be all over making this happen because I know I'd pay some green for it
