Although a day late or so news in regarding to iOS new version, it’s not yet too late to update your Apple’s devices to iOS 4.3.4.  iOS 4.3.4 is released to put a stop to a security flaw in regarding of PDF with the older iOS versions.  Apple releases the update in fearing of someone might be able to exploit the flaw and take control of users’ devices that rely on iOS.

When plugging your iPad 2 into your Mac, iTunes pops up and ask you if you want to update your iPad 2 software.  Answering yes once, and everything will automatically be taking care, right away.  The update process is smooth, and so you should not have any problem, unless you crazily turn off your machine during the update process or pull the USB cable between the device and the computer.  So, don’t do something silly like that!

Update:  iOS 4.3.4 could be jailbroken even though the release of it was only a day old.

According to Engadget, someone had already knew how to jailbreak the iOS 4.3.4 devices, but Apple had just released iOS 4.3.4 only a day or so.  Nonetheless, the update to iOS 4.3.4 still fixes the security flaw of PDF reader.  According to some commentators on Engadget, Apple’s devices could not forbid jailbreak since hardware exploit could be done no matter what, but I don’t know if that is true since I’m lacking experience in hardware department.  You should tell me something about that in the comments.

Anyhow, Jailbreak issue isn’t malicious for users in practical sense, since the users choose to Jailbreak their devices by hooking the devices up to their Mac and apply Jailbreak software.  Apple responses to the last Jailbreak with new update (i.e., iOS 4.3.4) since the last Jailbreak allowed hackers to take advantage of PDF reader’s security vulnerability that could couple with Safari to take control of users’ iOS devices.  Hopefully, the new Jailbreak which releases for iOS 4.3.4 will not expose any software security flaw so users will be safe from hackers.

Nonetheless, Jailbreak for iOS 4.3.4 is a testament to how jailbreak developers can move so quickly against Apple’s effort to lock users into iOS’s true environment.  Still, I don’t think it’s wise to use Jailbreak software unless you know what you are doing in term of not getting yourself to be hacked since Jailbreak software allows you to download almost anything that isn’t yet approved by Apple — in a sense those downloads cannot be trusted, unless you know something about the people that develop those Apple’s unapproved apps (i.e., could not be found in Apple App Store).
