During this night, winocm, the developer who is currently developing the solution of untethered jailbreak for iOS 6.1.3 si iOS 6.1.4, published the images above which confirm that iPhone 5 si iPad 3 were jailbroken on both versions of iOS. As you can see in the images, both are running the latest version of Cydia, the application confirming the identity of the devices and the iOS version they have installed. The developer is progressing rapidly and constantly to release its solution of jailbreak for users, but for now it is not known when it would be available.
Considering that the exploit used in this solution by untethered jailbreak no longer exists in iOS 7, the release of the solution will not affect the development of the future untethered jailbreak solution for the new version of the operating system. The new jailbreak solution is already compatible with iPhone 4 and iPhone 4S, and implementing compatibility with the rest of the iDevices should not be a major problem. Having said that, as soon as this jailbreak solution is released, I will let you know.
