Substitute v2.0 officially released, v2.0.1 also now available

At the end of November, hacker and unc0ver lead developer Pwn20wnd shared a Tweet indicating that Substitute — the primary tweak injection method for this particular jailbreak — would soon be updated to version 2.0 with a trove of improvements.

Without any sort of ETA provided at the time, no one could have guessed when Substitute v2.0 would launch. With that in mind, many unc0ver users were taken by surprise late last night when the update officially became available by way of Sam Bingner’s repository.

AutoLockX prevents apps from overriding Apple’s Auto Lock feature

As many iPhone owners already know, the iOS operating system provides users with a feature called Auto Lock that, when configured by the end user, can automatically lock the handset after a pre-defined amount of idle time. In other words, when your handset isn’t being actively used, it goes to sleep to save power and to secure your important data.

Auto Lock takes effect in most circumstances, however there are a few exemptions in which the feature gets overridden, such as during media (video) playback and while playing certain games. Some users like this because of its convenience, while others find it to be a concern both in terms of battery life and data security.

Apple unsigns iOS 14.2, 14.2.1, and 12.4.9, thwarting downgrades

After officially launching iOS 14.3 to the public last month with new features and improvements, Apple has closed the signing window for iOS & iPadOS 14.2 & 14.2.1, a move that prevents affected iPhone and iPad owners from restoring their handset’s firmware version to anything but the current iOS & iPadOS 14.3 release.

In addition to iOS & iPadOS 14.2 & 14.2.1, the company has officially started unsigning iOS 12.4.9, which prevents older handsets that are incapable of being upgraded to iOS or iPadOS 13 from downgrading from the newer iOS 12.5 release.
