Apple has been giving jailbreakers a hard time since the tech giant released the iOS 12 to the public in September 2018. It has been previously reported that there will be an exploit to be released soon although there is still no specific date, but for those that are waiting, it's recommended not to upgrade to iOS 12.1 as the company has stopped signing iOS 12.0.1.
According to Wccftech, Apple has stopped signing iOS 12.0.1 after the company released the iOS 12.1, which means that for those that have upgraded to the latest version can no longer go back to the older version. With that being said, for users who are waiting for a possible jailbreak release, it is best not to switch to the newest version of the software, especially that the company already ceased from signing it.
The iOS 12.1 is packed with new advanced features and additions such as eSIM support, a more competent Group FaceTime, and a lot more. However, users are more thrilled on having an iOS 12 jailbreak, which is a little difficult for developers and security researchers at this time as Apple has added more security on the software's framework.
The company produced a CoreTrust framework that's responsible for checking and verifying all signatures to ensure that they come from Apple. However, security researchers are now hard at work to have a successful iOS 12 jailbreak, including known developer and a member of the 360 Vulcan security team @S0rryMyBad, who will reportedly release the exploit very soon.
There have been a lot of attempts in the past few weeks, but nothing ever see the light of day although the security researchers have been doing their best to liberate Apple's advanced security phase. It is said that @S0rryMyBad's exploit is going to be the best exploit yet, which can be directly utilized in a jailbreak, making it relatively positive to break into the comprehensive security measures that Apple has set for its iOS devices.
Even the famous developer named Kudima or known as BigD reportedly submitted a WebKit RCE that can directly exploit to the GitHub repository, which can mean a possible jailbreak. But this too needs to be affirmed.
Developers and security researchers make a lot of money out of jailbreak exploit, so it's understandable that they should guarantee a working exploit for the iOS devices soon. For now, they recommend staying with iOS 12.0.1 or lower to easily jailbreak the device as soon as the exploit is released to the public anytime soon.
