iPhone and iPod touch Jailbreakers, Do Not Update to iOS 4.0.2 Until New Jailbreak Tool is Available
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.
