We know you are waiting for iOS 5, but in the meantime Apple has released iOS 4.3.4 to iPhone users across the world.

The new update, “Fixes security vulnerability associated with viewing malicious PDF files.”

It’s available for the iPhone 4, iPhone 3GS, iPad 2, iPad and iPod touch (4th and 3rd generation) devices.

Apple first acknowledged it was working on fixing the problem at the start of the month.

Earlier, Germany's IT security agency (the Federal Office for Information Security) warned that the exploit, as used by JailbreakMe, exposed "critical weaknesses" that could be used by cyber baddies to take a butchers at your iDevice's confidential data.

It stated that just clicking on an infected PDF file would be "sufficient to infect the mobile device with malware without the user's knowledge".

That loophole now appears to be closed.
