So one day after messin with winterboard, changin the UI, ********** stopped working. When I would try to "install" an app it would take me to the Apple store. It didnt do this before. And now my dock looks like the one used in ios 4 but i didnt upgrade.. and it still says im running version 3.1.2 under settings but something changed and I dont know what.. or how to get it back to normal..Cydia says "This device has SHSHs on file for iphone Os/ios: 4.0. Dont know what went wrong or how to fix it.. help?
