Amidst some controversy, name-calling and some really negative episodes recently in the jailbreak community, there's finally a jailbreak for all iOS 6.1.x and iOS 6.x flavors.
Recently, @wincom, a jailbreak developer announced (with proof) that he has jailbroken iPhone 5 (both GSM and CDMA) running iOS 6.1.4 which is the latest running iOS for the iPhone 5.
Insofar, we had Evas1on jailbreak working for iPhones running iOS 6.0, 6.1, 6.1.1 and 6.1.2. There were two updates to the iOS firmware: one for iPhone 4S (6.1.3) and one for iPhone 5 (6.1.4).
With these updates, Apple patched the software and kicked out the exploit. This rendered Evas1on tool useless to jailbreak any iPhone 4S or iPhone 5 running the latest iOS versions corresponding to the smartphones.
That there is/was no jailbreak for iOS 6.1.3/4 doesn't hit till you have to restore your iPhone and you end up doing a complete restore via iTunes (and instead of restoring to a custom firmware, you choose the latest).
When an update/restore gets your iPhone running on iOS 6.1.3/4, that's the dead-end. There's no jailbreaking beyond this point – at least so far.
Wincom has been actively tweeting about his work on jailbreak. The final announcement that came recently builds on another jailbreak on a iOS 6.1.3 exploit. With this, all iPhones that are iOS 6.x.x can now be technically jailbroken.
As far as iOS 7's jailbreak status is concerned, I am sure people are working on finding exploits but the scene will remain dull and under-the-hood till Apple launches iOS 7. Which is in about two days.
We're hoping that @wincom will release the jailbreak tool in the coming days. Subscribe to iGB to get the latest scoop on jailbreak.
