Couple of days ago Apple released iOS 4.0.2 and iOS 3.2.2 fixing the PDF exploit on all iPhone / iPod Touch and iPad devices running iOS firmwares. Although upgrading your iPhone or iPad to iOS 4.0.2 patches the PDF exploit, yet it also removes the jailbreak (JailbreakMe) and unlock (Ultrasn0w) on your device. Jay Freeman (Saurik) has released his own PDF Patch which completely close the PDF hole on all devices running iOS 4.0 / 4.0.1, hence allowing you to patch the PDF exploit without updgraing your device's firmware to iOS 4.0.2.
PDF Loading Warner is another Cydia app which warns you before downloading any PDF file on your device but it do not patch the PDF exploit. So, to actually patch the PDF hole, all you need is to install the PDF Patch via Cydia. Just search PDF Patch in Cydia on your jailbroken device and install it. This will save you from hackers who can use this PDF vulnerability to hack your device. [via Dev-Team Blog]
