iOS isn't known for its ability to be customized, so it's no surprise that you can't change the sound for third-party notifications without a jailbreak tweak. CustomNotificationSound by snakeninny, the developer who brought us LowPowerBanner, does exactly that.
Semaphore has been on a roll lately, as shown by the release of yet another TinyUmbrella beta build, and this version contains a significant new feature. You now have the ability to save SHSH blobs directly from a local device. This means that if you're on a jailbreakable firmware like iOS 8.1.2, you can save the 8.1.2 blobs even though Apple is no longer signing that firmware version.
iOS 8.1.2 met its end today, as Apple pulled the plug on its signing status. This means that iOS 8.1.2 can no longer be installed on a device, and as such, you can no longer jailbreak if you restore your device. Jailbreakers will need to stay where they are on iOS 8.1.2 if they want to keep their jailbreaks.
It is now possible to jailbreak iOS 8.1.2 using a Mac, and this has been confirmed by iDownloadBlog. Up until this point, no Mac option existed for jailbreaking iOS 8.1.2, but that is no longer the case. A new tool entitled PP jailbreak for Mac has surfaced, allowing Mac users to enjoy what Windows users have been enjoying for some time now. Inside, we have a tutorial that shows how to jailbreak iOS 8.1.2 using OS X with the PP jailbreak for Mac.
TaiG has released version 1.2 of its iOS 8 jailbreak tool, and it's now capable of jailbreaking iOS 8.1.2. As has been the norm with the past few jailbreak releases, this is a Windows only jailbreak tool. If you're running Windows, you can follow our step-by-step tutorial. If you're on a Mac, you can use our virtual machine tutorial to run Windows on OS X and jailbreak.
As expected, TaiG has been updated to support the iOS 8.1.2 firmware. A few prominent developers sent tweets out earlier today stating as much, but now we have the proof in the form of an official release. You can find the updated TaiG jailbreak tool on our downloads page.
According to several reliable sources within the jailbreak community, it looks like the TaiG jailbreak will remain working after the iOS 8.1.2 update. Although the TaiG tool will need to be updated to include iOS 8.1.2 support, it shouldn't take any new exploits or re-enginering on the developer end to include support for iOS 8.1.2.
Apple has released iOS 8.1.2 this afternoon with a handful of bug fixes and other improvements. Specifically, the release notes say the update addresses an issue where ringtones purchased through the iTunes Store may have disappeared from users' devices.
You can access the new firmware over the air via Settings > General > Software Update, or via iTunes by connecting your iPhone, iPad or iPod touch to a computer. But as usual, we recommend that users who are jailbroken, or plan to jailbreak, avoid the update for now.
