Apple has pushed out the new iOS 4.0.2 firmware for iPhone 4, iPhone 3GS, 3G and iPod touch 3G / 2G. This new firmware is basically a security update which patches the PDF exploit used by JailbreakMe to jailbreak all iOS devices. Now if you care about your security, you can go ahead and update now but doing so will make your iPhone 4, 3GS and iPod touch 3G / 2G unjailbreakable until a new jailbreak tool is available.
Incase you decided against updating to keep your jailbreak alive, make sure you install PDF Loading Warner app which will keep your browser safe from this vulnerability.
YOU HAVE BEEN WARNED ! We will update you as soon as we will have more on this. Stay tuned!
UPDATE 1: The video embedded below shows that JailbreakMe doesn’t work on iOS 4.0.2:
