A member of the Chronic Dev Team has taken the exploit that allowed for an "untethered" jailbreak of iOS 5.0.1 on A4 devices and made it work on A5 devices, as demonstrated by a video showing an iPhone 4S running the stock operating system rebooting with its jailbroken apps (including Cydia and iFile) intact, reports hacker pod2g. The new technique is planned for a public release in the near future, though pod2g was not specific about when.
