JailbreakMe security hole closed
Apple on Wednesday released updates to its iOS software, v4.0.2 for the iPhone or iPod touch and v3.2.2 for the iPad. The updates appear to fix a security exploit that had allowed devices to be hacked using a PDF document. The PDF vulnerability allowed users to quickly jailbreak a device by visiting JailbreakMe.com via Mobile Safari.
The iOS updates are available as free downloads from iTunes. iOS 4.0.2 is compatible with the iPhone 4, iPhone 3GS, iPhone 3G, and second- or third-generation iPod touch, while iOS 3.2.2 works with both iPad variants.
