That tinkling sound hear is the sound of millions of iOS device owners rushing to sync with iTunes, as Apple has released iOS 4.3.2.
The update addresses just a couple of issues. It corrects a problem with blank or frozen video during FaceTime calls (potentially resolving a strange bug that some users have complained about) and it fixes an issue that prevented some international users from connecting to 3G networks using the iPad Wi-Fi + 3G.
The update also includes a number of security-related patches, such as blacklisting fraudulent security certificates issued by Comodo, a patch for a vulnerability in QuickLook related to maliciously crafted Microsoft Office files, and several fixes for protecting against maliciously crafted Websites.
The release of this iOS update comes less than a month after the release of the similarly bug-fix-ish 4.3.1 and supports the GSM iPhone 4, the iPhone 3GS, the iPad and iPad 2, and the third- and fourth-generation iPod touch.
To download and install the update – which weighed at upwards of 600 MB for several Macworld staffers –connect your device to your Mac or PC and click Check for Updates in iTunes.
