Apple iOS 4.0.2 for iPhone Patches PDF Exploit

Apple's pushing out iOS 4.0.2 for iPhones and iPod Touches and iOS 3.2.2 for iPads, an update that patches the previous versions' PDF exploit and wipes out your iPhone's unlock and nice new jailbreak.

The update, which is showing up in iTunes now, doesn't bring any new features, just a patch for the recently-exposed PDF vulnerability (the one used by JailbreakMe), so if you weren't super worried about being susceptible—or if you want to keep your jailbreak or your iPhone unlocked—you might not want to jump on this one just yet.
