So why upgrade to iOS 6.1.2?
Its change log says it all – it fixes an Exchange calendar bug that could result in increased network activity and reduced battery life.
Does it patch the lockscreen passcode vulnerability recently discovered on iOS 6.1?
Sadly though, no. That vulnerability still exists even after upgrading to iOS 6.1.2. Well, I’m not sure with the iPhone 4S and iPhone 5, but as far as the iPhone 4 goes, I can confirm it’s still there.
Now, on to the most important question, is iOS 6.1.2 jailbreak-able?
Thankfully, yes! All you need is the latest release of evasi0n – evasi0n 1.4 – and you’re good to go.
