Pwn20wnd’s unc0ver jailbreak tool has enjoyed a monopoly over iOS 12.0-12.1.2 for months, albeit with limited handset support due to the lack of Cydia Substrate support for A12(X) devices. On the other hand, that could all change in the very near future.
The Sileo Team on Thursday Tweeted a teaser of what appears to be the Sileo app running on the upcoming Electra12 jailbreak, citing it to be a speed demonstration of the Cydia alternative for package management on jailbroken handsets.
