Apple has released iOS 4.3, the latest version of its operating system for iPhones, iPads and the iPod Touch, and is urging customers to download and install it immediately to avoid serious security problems.
The update includes several patches for critical security bugs that could be exploited by an attacker to run malicious code on a user's mobile device, the security firm Sophos reported.
The devices can be exploited via maliciously crafted websites and manipulated Tagged Image File Format (TIFF) image files, Apple wrote on its website.
Unfortunately for some Apple fans, the iOS 4.3 update is compatible only with the iPhone 3GS, iPhone 4 and the later-generation iPod Touch, as well as both the iPad and iPad 2.
First- and second-generation iPhone and iPod Touch users cannot install the new iOS, and therefore remain susceptible to the attacks.
“If you were looking for an excuse to upgrade your iPhone or iPod touch — maybe you’ve just been given a good one by Apple,” Sophos wrote on its blog. “But if you were happy with your iPhone 3G, I doubt you’re feeling too good about having to reach into your pocket.”
Users can download the updated iOS 4.3 through iTunes. Sophos said the new iPad 2 will include the updated iOS 4.3 when it is released tomorrow (March 11).
