I've been jailbroken for months on 4.2.6 with Greenpoison. Yesterday I downloaded a few things from Cydia, and now my JB doesn't work properly. It still has all of the apps, and cydia still works as does MyWi, but there's nothing visually jailbroken. My carrier logo is gone, there are no jailbroken apps in my settings. Winterboard is there, but it doesn't work. I deleted the apps I downloaded yesterday from within Cydia. Any ideas?
