Well, that didn't take long.
A well known jailbreaking expert, operating under the moniker of iH8sn0w, released a video online last night revealing the untethered jailbreak of iOS 9, which was announced only a few days ago as part of the Apple iPhone event.
At the event, Apple CEO Tim Cook revealed three new operating systems -- OS X 10.11 El Capitan, iOS 9 for iPhones and iPads, and watchOS 2 -- which are due for release publicly, with iOS 9 expected for rollout on 16th September.
The iPad and iPhone maker has released the Gold Master seed for Xcode 7, iOS 9, OS X El Capitan, and watchOS 2 to developers through the Apple Developer platform -- and it is this version iH8sn0w has enjoyed tampering with.
iH8sn0w, the developer of jailbreak tools including f0recast for Windows and sn0wbreeze for iOS, said they were "a little annoyed" at some of the new functions within the operating system's latest evolution, but was still "very surprised at how similar it is to iOS 8 internally."
The video below shows the untethered jailbreak take place on an iPhone 5 running the iOS seed, including Verbose booting, code injection and a custom boot logo.
The hacker explained:
"Worth noting, iOS 9+ arm64 iDevices now enforce a checksum on __TEXT/DATA.const regions of the kernel through the use of TrustZone. Modifying said sections will cause the device to panic (either at kernel or EL3 will force a reboot if the kernel refused to gracefully panic). Essentially, it's KPP (Kernel Patch Protection).
You can race it though if you want to play with things. Just be quick!
Also, there should technically now be two additional partitions (baseband_data [s1s3] and logs [s1s4]) but didn't really bother with those as they weren't critical."

While iH8sn0w does not plan to release his work to the public -- as this could result in Apple patching the vulnerabilities relating to the hack -- the case study does show that other developers and breakers are likely to be able to jailbreak their own iOS devices.
