iOS 4.0.2 for iPhone and 3.2.2 for iPad Patches PDF Exploit

Apple is pushing out updates for iPhones, iPod touches and iPads. The update does not add any new feature, but fixes the known PDF exploit and removes your jailbreak.

The update makes it tough for the simple and extremely popular JailbreakMe to operate as it was based on the PDF exploit. If you are not worried about the exploit and want to keep your device jailbroken, don’t update.
