Apple users with Jailbroked devices constantly had an upper-hand when it turns up to upgrade/downgrade the iOS updates for iPhone, iPad and even the iPod Touch. Recently we posted about downgrading latest iOS 10.3.1/10.3 for the Jailbroked devices.
Today Apple called off signing iOS 10.2.1 and iOS 10.3 that signifies you can’t go for a downgrade or restore to those firmware versions anymore. Apple makes this step while there were positive reports on the recent firmware update iOS 10.3.1 and a newly seeded 10.3.2 to the developers.
It will be interesting to see what in terms of jailbreaks as Apple recently announced the APFS file system with the new iOS 10.3 launch.
