Apple (finally) released iOS 4.0.2 and iOS 3.2.2 firmware to patch the PDF exploit, the very large security holes exploited by @comex in the 2nd incarnation of jailbreakme.com. The only problem is they outright abandoned iPhone 2G and iPod Touch 1G users! and on the other hand iOS 4.0.2, 3.2.2 is NOT jailbreakable ATM which means all other iDevices running iOS 4.0.1 or lower are still vulnerable.
Even though Apple acknowledges in their security update the severity of these holes, they left iPhone 2G and iPod Touch 1G owners high and dry — completely vulnerable to truly malicious variants of jailbreakme (these variants aren’t out yet, but they’re sure to come!).
Luckily for Apple, the Jailbreak community isn’t so callous. All the iPhone 2G, iPod Touch 1G and all other iDevices users running iOS 4.0.1 and do NOT want to update to iOS 4.0.2 to keep their iDevice jailbroken, can still patch the PDF exploit without updating to iOS 4.0.2 firmware.
Saurik, the guy behind Cydia and a respected member of the Dev-team has released the PDF Patch, a fix for PDF exploit, in Cydia. The PDF Patch is now available in Cydia for free and you can download and install it now.
PDF Patch fixes the security hole that let Comex develop JailbreakMe 2.0 and could potentially be used to inject malicious software on your device. Open the Cydia, search for PDF Patch and install it. That’s it! you have secured your iPhone 4, 3GS, 3G, 3G, iPod Touch 3G, 2G, 1G and iPad without updating to iOS 4.0.2 or iOS 3.2.2.
NOTE: All those users who have updated their iPhone/iPod Touch to iOS 4.0.2, and iPad to iOS 3.2.2, there is no need to install this patch. This PDF patch is for all iPhones/iPod Touches running iOS 4.0.1 or lower and iPads running iOS 3.2.1 or lower.
To test that it’s working properly, visit jailbreakme.com again. After you slide to jailbreak, you should no longer see a dialog box pop up (you’ll just see the star background). That means you’re no longer vulnerable!
