As promised, the Pangu team has updated the Pangu iOS 8 – iOS 8.1 Untether package in Cydia to version 0.4 today. The update includes a fix for random application crashes on 32-bit devices—iPod 5, iPhone 4s/5, iPad 2/3/4 and the original iPad mini—particularly with Safari.
The update follows version 0.3, which was released over the weekend to fix an overheating issue in jailbroken 32-bit devices. The update was pulled shortly after it hit, due to users reporting "mild to serious issues" with the package, but the issue was resolved and it was re-posted.
