Critical bug fix for Substrate Safe Mode released for checkra1n and unc0ver users

If you’re using a modern jailbreak that uses Cydia Substrate as its primary means of tweak injection, be it checkra1n or unc0ver, then today might be a good time to fire up your preferred package manager and refresh your sources.

Substrate Safe Mode appears to have been updated to version 0.9.6003 with a critical bug fix. The checkra1n team shared the announcement in a Tweet delivered early Friday morning:

Planning to use unc0ver to pwn your iOS 13.0-13.3 A12(X)-A13 device? Get AltStore now

The unc0ver jailbreak is so close to publicly supporting iOS 13.0-13.3 on A12(X)-A13 that we can almost taste it. Support for Brandon Azad’s new oob_timestamp exploit was pushed into internal beta testing yesterday afternoon, and according to Pwn20wnd, unc0ver could be publicly available in the next 24 hours or so if everything goes smoothly.

Assuming you managed to downgrade to iOS 13.3 from iOS 13.3.1 before Apple stopped signing it yesterday or already had some version of iOS 13 installed between 13.0-13.3, you’re probably wondering what you can do to prepare your jailbreakable handset. If that’s the case, then we’d advise setting up AltStore on your Mac or PC.

Apple stops signing iOS 13.3 as updated unc0ver jailbreak nears public release

Apple must’ve caught wind about Pwn20wnd’s fast-paced progress on updated the unc0ver jailbreak for iOS 13.0-13.3. Not even a few hours after internal beta testers hyped the project on Twitter with the #unc0ver hashtag, Apple officially closed the signing window for iOS 13.3 to prevent downgrades from iOS 13.3.1.

Apple’s swift blow to iOS downgrading on Wednesday was somewhat out of character for the company because it transpired much earlier in the day than usual. While Apple regularly unsigns older firmware, the abruptness of iOS 13.3’s unsigning after Pwn20wnd’s slurry of announcements regarding unc0ver suggests that Apple intended to contain the jailbreak situation before it could reach the masses.

Unc0ver enters internal testing with support for A12(X)-A13 running iOS 13.0-13.3

Hot off the heels of a plethora of teasers that have been shared over the course of the past couple of weeks, Pwn20wnd has officially commenced an internal beta testing phase for the unc0ver jailbreak with iOS 13.0-13.3 support on A12(X)-A13 as of Wednesday afternoon – a feat made possible with Brandon Azad’s oob_timestamp tfp0 exploit.

The news surfaced by way of Pwn20wnd’s official Twitter account, which earlier this morning noted that unc0ver would soon move into the internal testing phase. A few short hours later, internal testing officially began:

Castmary gives your iPhone an iPad-like grid App Switcher

The App Switcher experience on the iPhone leaves a lot to be desired, especially if you’ve ever used an iPad before. That said, it’s mind-blowing that Apple hasn’t done anything about this yet.

If you’re tired of waiting for Apple to implement an official solution, then you can now take advantage of a new free jailbreak tweak called Castmary by iOS developer Simulation to get an iPad-style grid-based App Switcher on your iPhone or iPod touch.
