Well that was short-lived. After much publicity, the PDF exploit that jailbreakme.com utilises (that site and others) to jailbreak your iPhone has been fixed by the big A. Apple this morning released the 4.0.2 update to fix that specific issue. That is all. No antenna fixing issues. No 3G painkillers. Nothing. Just a PDF, font-subsystem fix to keep Apple’s iPhone and iOS happy. Oh, and to stop youngsters (both real and young-at-heart) from breaking Apple’s retail display iPhones.
