The ChronicDevTeam courtesy of member @DHowett, iOS developer, has a video showcasing an untethered jailbreak on an iPhone 4S, running on iOS 5.0.1.
This sort of a jailbreak solution has been available on A4-powered iDevices but, up until now, it had its ups and downs on the A5-powered iPad 2 and iPhone 4S.
The video seems real. We’re demonstrated a reboot after which Cydia is still functional and last but not least we’re shown the different antenna design and a running Siri version.
Here’s the video if you want to check it out for yourselves.
As to when the untethered jailbreak for A5 devices will be available the developer says “Only a few to wait now.” Are those few days, few months we don’t know.
The other bit of news is that the security loop-hole found in iOS 5.0.1, which allows the untethered jailbreak on A5 devices has been patched up in iOS 5.1 beta 3. In layman’s terms this means no untethered jailbreak of iOS 5.1 in the foreseeable future.
So if you haven’t updated to iOS 5.0.1 and wish to use the untethered jailbreak, you should steer clear of all upgrading when iOS 5.1 becomes available publicly.
