Apple just released iOS 8.3 for public. You can upgrade your device to iOS 8.3 via iTunes. Apple also released OS X 10.10.3 to the public today. New iOS 8.3 was tested on Apple developers and members of Public beta program since February with 4 beta versions. One of the most remarkable improvement is wireless carplay feature. iOS 8.3 can connect Car play via Wi Fi to your vehicles head unit.
You can download iOS 8.3 on any compatible iPhone iPad or iPod using iTunes or device itself at Settings > General > Software update. We recommend to stay away from updating for Cydia lovers if your want to preserve the current jailbreak. Once you are stepped into iOS 8.3, there’s no way out. Hopefully popular jailbreak developer i0nic (Steffan esser) just has tweeted that Apple seems doesn’t fixed the allow-dylibs-to-override-cache vulnerability in iOS 8.3hich we can have a hope of iOS 8.3 jailbreak. But wait until we confirm the jailbreak capability of new iOS 8.33.
