Apple released iOS 6.1.2 a couple of days ago that fixed the annoying Microsoft Exchange bug plaguing numerous iOS devices. However, it didn't address the recent lock screen exploit that allows nosy eyes to get a peek at your contacts and photos. However, iOS 6.1.3 beta 2 was just seeded to developers, and it looks like this update will fix the vulnerability.
This is the third minor update to iOS 6.1 alone in just a few weeks, so it seems Apple is getting better at addressing issues in a quicker and more efficient manner. This latest release was just seeded to developers, and it's actually the same update as iOS 6.1.1 beta 1, but is being rebranded as iOS 6.1.3 with a few more fixes added on, including the lock screen bug.
The update also includes several enhancements to the Apple Maps application for Japan users that we saw earlier this month. There's no word on when the official iOS 6.1.3 update will roll out to all users, but it should be fairly soon. There's also no word on whether or not this new update patches up the evasi0n jailbreak, so stay tuned for that.
The lock screen exploit that iOS 6.1.3 will fix allowed people who got a hold of your phone to bypass the lock screen and gain access to your contact list, as well as any photos stored on your iDevice. While the hack itself takes a bit of practice to learn, anybody could easily learn the trick to get a hold of your contacts.
