iOS hacker Winocm has just posted a video of iOS 7.1 untethered boot on a device that looks like an iPhone 4S. If you don’t know, the term ‘untethered boot’ is used for a jailbroken device with ability to boot without connecting to a computer. On the contrary ‘tethered boot’ requires you to connect your jailbroken device to a computer every-time you reboot your iOS device or its battery dies. If you don’t connect it to any utility like redsn0w etc. for a tethered boot, you won’t be able to access all the tweaks/apps installed from Cydia or sometimes you can stuck into respring loop.
The video simply shows an untethered boot on iPhone 4/4s (ambiguity due to same form factor and unclarity of video) running iOS 7.1. Here’a the tweet from @winocm:

Released video doesn’t show Cydia running or even its icon, but that doesn’t mean it has nothing to do with the jailbreak. Also it is unclear at the moment whether this exploit is limited to A4/A5 devices or is also applicable to latest devices running A6 and A7 processors. We hope that after this we are a step more closer to possibility of an iOS 7.1 untethered jailbreak.
We will keep you updated with the progress on the iOS 7.1 jailbreak. Stay tuned!
