Well we can’t say we didn’t see this one coming, last week we posted that Apple would most likely release and iOS update to deal with the JailbreakMe vulnerability which let users jailbreak their iDevice simply by visiting a website. Well now it looks like Apple has plugged the PDF exploit in iOS with the now-available iOS 4.3.4 which you can download via iTunes. The PDF exploit was used by JailbreakMe, so if you’re planning to use it to jailbreak your iPhone, you’ll want to avoid this update.
The iOS 4.3.4 download is now available through iTunes for the iPhone 4, 3GS, iPad 1 and 2 and third- and fourth-generation iPod touch. Verizon iPhone users will get the same fix via the iOS 4.2.9 update (build 8E501).
