Apple on Tuesday released iOS 6.1.3, a minor update to the operating system that powers iPhones, iPads, and iPod touches. Included in the update is a fix for a recently discovered means of breaking past the lock screen, along with Maps improvements for Japan.
Apple's iOS 6.1.3 update also plugs the exploits that allowed the Evad3rs Dev Team to release its evasi0n untethered jailbreak, so those who want to continue using the jailbreak will need to avoid updating. Apple did, however, credit the team for finding the exploits in its iOS 6.1.3 security note.
As per usual, you can install the update via the Software Update section of the Settings app on your iOS device, under General, or you can update via iTunes.
The update comes hot on the virtual heels of iOS 6.1.2, which fixed an Exchange calendar bug that could result in increased network activity and reduced battery life.
Apple released iOS 6.1 on 28 January, and was forced to roll out iOS 6.1.1 and iOS 6.1.2 in the coming weeks. The first of the updates, iOS 6.1.1, became available to iPhone 4S owners on 11 February in order to fix the 3G issue experienced by some users after updating to iOS 6.1. On 8 February, Vodafone has warned its UK iPhone 4S customers not to upgrade to 6.1 due to performance issues with 3G. iOS 6.1.2 arrived on 20 February.
