Look Into the iOS 15 Jailbreak
You'll want to avoid iOS 15 if you're currently jailbroken or if you want to jailbreak.
The unC0ver tool works with newer iPhone models including the iPhone 12 series which is huge news for those who bought one of Apple's flagships from 2020.
Unfortunately, unC0ver only works with iOS 14.3 and below. Checkra1n works with iOS 14.5 and below, but it's currently in beta so it may not be worth the trouble.
If you're thinking about jailbreaking your phone on iOS, you'll want to weigh the pros and cons before you take the plunge, especially now that an iOS 15 jailbreak is evidently on the horizon.
Hackers say they're planning to release an iOS 15 jailbreak, but it looks like it will only work with older versions of the operating system (iOS 15.0 to iOS 15.1.1) at first. So, if you want to jailbreak, make sure you avoid newer versions of iOS 15.
