Is It Worth Upgrading to iOS 8.3
It is worth mentioning that the latest iOS version iOS 11 will be released in this autumn, and the oldest iOS version Apple offers certification to, is iOS 10.3.3 for iPhone, iPod, and iOS 10.3.2/iOS 10.3.3 for iPad. So, now you are only allowed to Downgrade from iOS 11 to iOS 10.3.3/10.3.2 >.
On April 8, 2014, Apple Rolled out its iOS 8.3 as a public release. The new update delivers performance improvement, tons of bug fixes and emoji keyboard, new language support for Siri etc.
However, as more users who upgraded their devices to iOS 8.3 encountered many new issues as well. Like lower battery life, password settings missing, Wi-Fi issue, Cellular Data issue, app problem, performance problem, Touch ID problem, message problem etc. The worse issue for our iMobie friends is that Apple blocked access of the entire sandbox directory which ruined normal functions of PhoneClean. It seems iOS 8.3 update takes away more than it gives to users.
To get PhoneClean normal functions back and for those users who are angry about iOS 8.3 bugs or adapted to iOS 8.2, we prepare a plan for you to get rid of these troubles: Downgrade iOS 8.3 to 8.2 on your iPhone, iPad and Pod touch.
Downgrade to iOS 8.2 from 8.3
The downgrade supports the following list of Apple devices running iOS 8.3 firmware:
iPhone: iPhone 6, iPhone 6 Plus, iPhone 5s, iPhone 5c, iPhone 5 and iPhone 4s.
iPad: iPad Air 2, iPad Air, iPad 4, iPad 3 and iPad 2.
iPod touch: iPod touch 5.
Note: downgrading from iOS 8.3 to 8.2 is only possible when Apple is still signing the iOS 8.2 firmware, but once that signing window is closed, the downgrade to iOS 8.2 will not be possible anymore. Unfortunately nobody knows how long it will last, so downgrade with the tutorial below while you still have time.
