Apple updates iOS to fix security flaw

Apple has released a new version of the iOS to fix a major security flaw. iOS 4.0.2 for iPhone and iPod touch and iOS 3.2.2 fixes a problem first highlighted by Jailbreakme.com which would allow a PDF file to execute arbitrary code on your iOS device.

In the case of Jailbreakme.com, the security hole was used to jailbreak the iOS device, a relatively benign operation. However, that same exploit could be used for less innocent purposes.

If you plan to jailbreak your iPhone, don't upgrade to this version of the OS. However, if you do jailbreak your iPhone with Jailbreakme, you should still do something to protect yourself from this exploit.

The only solution I've seen is an app called PDF Loading Warner that will warn you if Safari is loading a PDF. It's available for free on Cydia. (For more on PDF Loading Warner, check out this Cult of Mac post). Note that this app does not fix the flaw. It only warns you if Safari is trying to load a PDF and gives you the option to prevent the PDF from loading.
