my buddy has a JB 3GS, sucker downloaded some cracked apps trhough a few cydia repos, his device now acts very weird, even after deleting the mentioned apps, mobile substrates are still embeded on the phone, so the apps continue to ramdomly appear . We deleted everything via shsh and still the phone freezes randomly every few minutes asking for a respring. He now has to restore and reJB. ( evil laugh) hahaha stay away from "free" apps people, just a little advise. Peace.
