One can easily gauge the demand for Apple iOS 6.1.3/6.1.4 jailbreaks with success of fake Apple iOS scams like Firestorm and Silv3rWind. Apple patched the evasi0n jailbreak with iOS 6.1.4 update making it unjailbreakable, but there is some good news as Apple iOS 6.1.4 has been successfully got jailbroken on iPhone 5 and the report has been verified by multiple users. A new name to the scene Developer Winocm achieved a successful untethered jailbreak for iOS 6.1.3 last week, and has now tweeted an image of Cydia running on iOS 6.1.4 and iPhone 5. He also went ahead and made public the source-code to replicate the success for others as shown below.

Wincom has made public some code which others are reporting to be working successfully, however this is far from a user-friendly public jailbreak method. However, since dev's now have there hands on the exploit we can expect pretty GUI's to get them working for everybody soon.
