Apple has released an official version of iOS 10.3 for the iPhone, iPad, and iPod touch which includes bug fixes and security improvements. What’s new in iOS 10.3?
With the release of its new version of iOS 10.3, many of you have already downloaded the latest iOS version of 10.3 on your iPhone, iPad and iPod touch to get some new features and improvements but if you are a jailbroken user and waiting for iOS 10.2.1 Jailbreak in future then we recommend you to downgrade immediately iOS 10.3 to iOS 10.2.1 firmware.
So for jailbreakers, do not upgrade to the latest version of iOS 10.3, it’s better to stay on lower iOS like iOS 10.2.1, 10.2(for iPhone 7-7 Plus) if you want to jailbreak in the near future. And if you are already on iOS 10.1, iOS 10.1.1, 10.2. Here’s how to jailbreak iOS 10.1.1 with Yalu and Cydia Impactor.
