iphone 4s jailbreak cydiaiPhone 4S users who updated to iOS 7.1 will apparently be able to jailbreak their iPhone once again. Last week hacker Winocm posted a video on YouTube showing his iPhone 4 running a complete untethered jailbreak. His phone was running Apple’s new iOS 7.1 update. Later that day another famous hacker iH8sn0w challenged Winocm for a iOS 7.1 jailbreak for A5 devices. “Does this mean I have to bust out my camera and shoot an untethered 7.1 A5 boot?” hacker iH8sn0w tells Winocm on Twitter. Today, after challenging Winocm, iH8sn0w has confirmed that he has an iPhone 4S on iO 7.1 fully jailbroken. “Can you jailbreak 7.1 iPhone 4 s or only 4 ??,” asks a Twitter user to iH8sn0w. “Well my 4S is jailbroken on 7.1 atm.,” responded the hacker. So the hacker has an iOS 7.1 jailbreak. Now we have to wait until he release it to the public, which no date were given.
