My phone had been jailbroken for about 4 months w/o an issue. Last night my applications were randomly repositioning themselves every half hour or so. So I re-quickpwn'd it this afternoon, but now I cannot see Cydia. I ssh'd into it, and in the /Applications folder Cydia exists, but I cannot see it on my phone's screen. Installer is visible, but no Cydia. I've got a feeling that it's something to do w/ Categories because I had Cydia in a folder, but there isn't a Categories folder in /Applications. Please help!
