Apple has released a software update iOS version 4.3.4 for iPhone 4, 3GS, iPad 2, 1, and Pod touch.
The main objective of this version is to prevent the hacking in Apple iOS devices which occurs through malicious pdf file. Another objective is to prevent the jailbreaking which occurs as a consequence of the previous effect.
In previous versions, the iOS devices are easily vulnerable to attacks which happens because of mishandling of fonts embedded in pdf file. It is quite common to download a pdf file through e-mail or web pages. Sometimes the downloaded file may be malicious and there is possibility that the file could inject malware into the iOS device — that gives a chance for the hackers to access the hardware.
Again the previous problem leads to jailbreaking of iOS. (Jailbreaking is the process of hacking the iOS and as a consequence it allows the user to install non-Apple approved software in the Apple device — which makes it less secure.)
Both the problems have been solved by this updated version.
The download will take roughly around 25 minutes. This is due to the fact Apple wants its user to download the entire OS file rather than just the updated one. Once the upgrade has been done, your device will free from any malicious file.
Apple has made many updates in its iOS but this version of iOS will leave a huge impact in the minds of the user. Be risk-free and secure by updating the your iPhone, iPad or iPod to iOS 4.3.4.

Update: We can confirm that only untethered jailbreak (Using JailbreakMe 3.0) doesn’t work with this update. However, 4.3.4 has already been jail-breaked using RedsnOw and PwnageTool.
