14 DAY TRIAL // If you planned on downgrading your iPhone, iPad or iPod touch device to iOS 11.2.5, you should know that Apple recently stopped signing the firmware, which means you're now stuck with iOS 11.2.6, the latest stable version.
If you're running the latest iOS 11.2.6 software update on your iPhone, iPad, or iPod touch device, you will no longer be able to downgrade it to a previous iOS version, such as iOS 11.2.5, as Apple stopped signing the firmware on March 1st, 2018.
Of course, if you're using an iOS version prior to iOS 11.2.5, such as iOS 11.2.2 or earlier, you won't be able to upgrade to iOS 11.2.5 either. Instead, you'll have to upgrade directly to iOS 11.2.6, which is currently the only stable iOS software offered by Apple.
Apple released the iOS 11.2.6 software update on February 20, 2018, along with the tvOS 11.2.6, watchOS 4.2.3, and a macOS High Sierra 10.13.3 Supplemental Update to fix an issue where certain character sequences could cause apps to crash and improve support for external accessories with some third-party apps.
It's important to always have the latest iOS software version
Apple always recommends users to update their devices to the latest iOS operating system, and it forces them to do so by stopping signing previous iOS versions. It's a very good strategy and, until now, it worked flawlessly to keep iOS a secure and reliable mobile operating system for supported iPhone, iPad, and iPod touch devices.
If you're not running iOS 11.2.6 on your device, we suggest upgrading it as soon as possible by opening the Settings app, going to the General section, and then tapping on the Software Updates section. Also, make sure you have the latest software versions of your apps installed by accessing the Updates tab in the App Store app.
Apple is currently working on the next major update for its iOS 11 operating system, namely iOS 11.3, which is currently in beta testing. The company plans to release iOS 11.3 this spring to allow iPhone users to diable the deliberate performance throttling via new battery feature, as well as to bring enhanced AR experiences.
