Apple has finally fixed the PDF exploit used by Comex in JailbreakMe by releasing iOS 4.0.2 for iPhone 4, 3GS, 3G and iPod Touch 2G & 3G. This update will not upgrade your baseband version but still upgrading your iPhone or iPod Touch to iOS 4.0.2 will leave your device in an unlocked state as there is no official tool available yet which can jailbreak and unlock devices running iOS 4.0.2.
Tweet by iPhone Dev Team:
If you are on official carrier and don't want to jailbreak and unlock your device, you can upgrade to iOS 4.0.2 through iTunes. Just plug your iPhone / iPod Touch to your computer, start iTunes and hit the "Download and Install" button.
