Earlier today, Apple released iOS 4.3.5 for iPhone, iPad and iPod touch. The update, apparently critical given the fact that Apple released it less than a week after it released iOS 4.3.4, “fixes a security vulnerability with certificate validation.” The update, dubbed iOS 4.3.5 build 8L1, is compatible with iPhone 3GS & 4, iPad 1 & 2, as well as third and fourth generation iPod touch. iOS for the Verizon iPhone 4 has also been updated, and moved to version 4.2.10 build 8E600. To update your device, simply plug it to your Mac or PC, launch iTunes, and click on ‘Update’.
