Here we’re talking about the iOS 15.1.1 update released yesterday by Apple for a couple of devices and how that affects the jailbreak community. So the current release of iOS is iOS 15.1.1 with the build ID 19B81 available for the iPhone 13 and iPhone 12. For example, if you search for 11 Pro Max, you will see no such updates for it.
So only those devices, the iPhone 13 and 12, got the update. According to arsTECHNICA, the updates only improve call performances, so Apple’s own words iOS 15.1.1 improves call drop performance on iPhone 12 and iPhone 13 models.

So if your iPhone 12 or 13 used to drop calls a lot and had pretty poor call quantity, then this should improve the matter a little bit. The update is pretty small. It’s only 385 megs in size on iPhone 13 Pro, so it’s not a huge update, and it says that according to the release notes, iOS 15.1.1 does precisely one thing, and it addresses the dropped calls on iPhone 12, 12 mini, 12 Pro Max, 13 and all the other 13 variants.
So what about jailbreaking on those devices and not only? If you have, for example, one of the affected devices like iPhone 12 and you do have the update if you are already on 15.1, you are safe to update the 15.1.1 to get the patch. But only if you’re already on 15.2. If you are running 14 points, something like 14.8 or 14.7, 14.6 and so on, do not update.

But from 15.1 to 15.1.1, this seems to be only the change this bug fix. It doesn’t seem to have any security changes so that it wouldn’t affect jailbreaking. The bugs currently exist. For example, this one by Brightiup demonstrated but not released yet, works on 15.1.

And this one by 08Tc3wBB which also works on iOS 15 and is a zero-day but again not released yet because it’s zero-day it works on the latest versions seems to be working on 15.1.1.

So if you update from 15.1 to 15.1.1, it wouldn’t be a problem; however, I would not recommend you update from 14.8, 14.7 or stuff like that to 15.1 if you’re running 15.0 or 15.0.2. I would also not recommend you to update these bugs. However, if they get released. They seem to be working on all iOS 15 versions because they’re zero days.

So yeah, you might be safe in there, but I would not update if you’re on 15.0. So in terms of uncovering updates, it will still need the same bug for 15.1 and 15.1.1, So it changes nothing if you update the 15.1.1 from 15.1 if you want to get a bug fixed and the bug fix is quite essential to call dropping is not exactly quite pleasant so if you’re going to get it, you can if you’re running 15.1.
For the rest of the devices, for example, the checkra1n devices or the iPhone 11, 10X Max 10R, and so on, there is no 15.1.1 update because apparently, the bug is not present on those devices, so there’s no version for you to update.

However, checkra1n doesn’t support iOS 15 at all for the moment, so do not update the iOS 15 if your device runs a lower version even if it’s a checkra1n range supported device like iPhone 10 or lower because checkra1n does not support iOS 15 even though jailbreak for iPhone 5S through 10 iOS 12.0 and up it’s not precisely end up it’s up to 14.8 iOS 15 is not supported.
So even if you don’t have the 15.1.1 update, do not update the 15 anyways on any device because there’s no jailbreak available even on the checkra1n supported devices. So, for now, if you are running 15.1 on a supported device, do update the 15.1.1 to get the bug fixed because there does not seem to be any security change for jailbreak purposes.
