Apple Fixes iPhone Security Hole With iOS 4.0.2 Update [iPad Too]

By

iOS_update

The gaping security hole in Mobile Safari has been fixed with updates to Apple’s iOS operating system.

Apple has just updated iOS to 4.0.2 for the iPhone (and iPod touch) and iOS 3.2.2 for the iPad. The updates patch a security vulnerability that allowed Safari to run code embedded in PDF files.

The updates are available through iTunes. Click “Check for Update” to download.

If you are plannign to jailbreak your device, do it before updating. o not get surprised, if the latest firmware includes a baseband update as well. If that happens, it will block the ultrasn0w carrier unlock as well.

Obviously, the new iOS updates break the jailbreak at JailbreakMe.com, which exploited the vulnerability.

The updates may also contain new baseband firmware, which will break carrier unlocking. To jailbreak and unlock your iOS device, see our Jailbreak Superguide.

Here are the details from Apple:
