Firstly it was iPhone 4S running on iOS 6.1.3
and today iPhone 5 running on iOS 6.1.4... Just a few moments ago @Wincom the well known hacker and developer has just tweeted
a screenshot from his device showing Cydia installed on iPhone 5 running on iOS 6.1.4....
As you can see from the picture above, it shows Cydia from inside where it is written below "iPhone 5 (AT&T), iOS 6.1.4, Cydia 1.1.8"... This picture is a big prove that Wincom unreleased jailbreak too is a successful tool...
So this is a very good news.. Currently I can say we've got our hands on jailbreak for two devices which are iPhone 4S and iPhone 5 running on iOS 6.1.3 and iOS 6.1.4.
It appears as though winocm's work on the jailbreak has progressed to the iPhone 5 and iOS 6.1.4. At this time there is no ETA for release; however, you can follow iClarified on Twitter
