Following the release of iOS 9.0.2 for iPhone, iPad, and iPod touch this morning, Apple has closed the signing window for iOS 8.4.1 and iOS 9.0. This means that users can no longer downgrade from a more recent version of the operating system to either of those older builds.
When Apple releases a new version of iOS, owners of previous generation devices are always a tad hesitant to upgrade, worried that the added features will bog down their device and make it run slower than it originally did. While iOS 9 has been the quickest adopted version of Apple’s operating system yet, there are likely still some holdouts worried about device performance. YouTuber iAppleBytes has this evening shared videos comparing the performance of iOS 9.0.1 to iOS 8.4.1 on the iPhone 4S, iPhone 5, and iPhone 5S…
Apple has pushed out an iOS update to address issues users have experienced with the Setup Assistant app getting stuck on “Slide to Upgrade.” The 9.0.1 update also fixes a problem with alarms and timers failing to play, and setting up a cutom APN could disable cellular connections. There’s also a fix for Safari and Photos could distort a video if it was paused during playback.
iOS 9.0.1 is available from the Software Update section of the Settings app. Apple also released new betas of iOS 9.1 and tvOS today.
