Apple is seen to soon deploy the final build of iOS 10.3 following the recent release of beta 5 of the same. But the hope that a finalized iOS 10 jailbreak release will come after seems to be getting dimmer, no thanks to the giant leap that the upcoming OS upgrade represents.

With the iOS 10.3 release, Apple will also make official the new file system that will be in use for all compatible iPhones and iPads. All 64-bit iOS devices to run on iOS 10.3 will be governed by the File System APFS, which for the jailbreak community spells bad news.

According to App Informers, the moment File System APFS is in play jailbreaking will become next to impossible. "This new File System APFS will almost guarantee that a jailbreaker cannot get into the IPA files. In computer terms, IPA is the iOS Application Archive, and this breach is needed for a successful jailbreak," the report said.

It appears too that the downgrade path as workaround to a possible jailbreak will be closed down, again courtesy of the file system packed with v. 10.3. "Even if you downgraded to a previous operating system, it will still not work," the same report added, and somehow that means jailbreaking as we know it will reach its end.

But Yalu102 jailbreak maker Luca Todesco has committed that he will finalize the tool. Of note though that even when completed, the solution will only for those already using the jailbreak or those who opted to remain on iOS 10.2 and lower versions. The rest will most certainly get locked out.

Provided the projection above will prove correct, WCCFTech said iPhone and iPad users will get some form consolation and a big one at that. Initial testing of iOS 10.3 "showed faster boot up speeds and quicker app loading times," and credit goes to the new File System APFS.

"We expect the new file system to show major boost in performance in the final build of the operating system," the report said, hinting that the leapfrog will be more noticeable from iPhones and iPads released from 2014.

WCCFTech said beta 5 iOS 10.3 is likely the last prior to the release of the final build, likely paving the way for better iOS device performance but also the end of the jailbreaking era.
