Unless it's seen and touched with your own hands, take the internet as a grain of salt. UnthreadedJB is a joke, Sn0wFallJB "suddenly" fell off the face of the Earth after supposedly claiming to have a 6.1.3 tool ready, Winocm works at his own pace and does as he pleases, Evad3rs are working solely on 7, and ih8sn0w already said Sn0wBreeze will not support 6.1.3/6.1.4 outside of a tethered jailbreak for the 3GS NBR,4, and the 3GS OBR. Any other claimers are scams
