Just last Monday, Apple released iOS & iPadOS 15.5 to the general public with changes for Apple Cash and the Podcasts app, and as many would come to expect, this move also meant that Apple would stop signing the older iOS & iPadOS 15.4.1 in the near future.
Apple released iOS & iPadOS 15.4.1 last week with a fix for the battery drain issue that had been widely reported by a myriad of users on iOS & iPadOS 15.4 and to address some security holes that needed patching.
Following a rigorous beta period, Apple unleashed its iOS & iPadOS 15.4 software updates for iPhone and iPad last Monday with huge upgrades, such as being able to unlock an iPhone with Face ID while wearing a mask and support for Universal Control, among other things. As we come up on a full week after the release, it’s unsurprising to see that Apple has now stopped signing the previous release: iOS & iPadOS 15.3.1.
With the news of an iOS & iPadOS 15.0-15.1.1-compatible kernel exploit being released, many iPhone and iPad users who’ve been wanting to jailbreak their handset have subsequently started seeking ways to upgrade to iOS or iPadOS 15.1 or 15.1.1 while they still can. While DelayOTA can be a solid option for anyone who hasn’t saved .shsh2 blobs, those who have can alternatively use futurerestore to update to these firmware versions.
Apple last week publicly released iOS & iPadOS 15.3.1 with bug fixes and security improvements for iPhones and iPads alike. Consequently, we knew it wouldn’t be long until Apple closed the signing window for the older iOS & iPadOS 15.3 firmware.
After releasing iOS & iPadOS 15.3 to the general public last week with important bug fixes and improvements for iPhone and iPad users alike, the Cupertino-based company has just this evening closed the signing window for the predecessor iOS & iPadOS 15.2.1 firmware.
Apple is no longer signing iOS & iPadOS 15.2 as of Wednesday, a move on the Cupertino-based company’s part that will stymie individual users’ attempts to restore or downgrade their iPhone or iPad to this particular firmware using either Finder on macOS or iTunes on Windows.
Apple just this evening stopped signing iOS and iPadOS 15.1.1 (for the iPhone 12 and 13 lineups) and iOS and iPadOS 15.1 for all the rest of the company’s mobile devices after releasing iOS and iPadOS 15.2 just last week.
Apple released iOS 15.1.1 for the iPhone 12 & 13 lineups a couple of Mondays ago with an important bug fix pertaining to dropped phone calls. Although I hadn’t experienced this problem myself, it was obviously experienced by enough users that it warranted a resolution from the OEM.
Apple last Monday released iOS & iPadOS 15.1 to the general public following a lengthy beta testing period with a bevy of enhancements for the company’s mobile operating systems. Those enhancements comprised of SharePlay, support for COVID-19 vaccination cards in the Wallet app, an automatic macro toggle for the Camera app, and a plethora of bug fixes among other things.
Apple released iOS & iPadOS 15.0.2 the previous Monday with bug fixes and security improvements for most modern iPhones and iPads, and now that about a week has passed, the Cupertino-based tech company has closed the signing window for the older iOS & iPadOS 15.0.1 firmware.
Apple released iOS & iPadOS 15.0.1 on October 1st, marking the first update to the company’s new mobile operating systems with bug fixes. Notably, this update resolved a problem with Unlock with Apple Watch not working correctly with the brand-new iPhone 13 lineup – an exceptionally valuable feature amid a raging pandemic in which mask-wearing has become a common sight.
Now that some time has passed since Apple released iOS & iPadOS 15.0.1, it’s no surprise to see that Apple is closing the signing window for the original iOS & iPadOS 15.0 firmware that launched to the general public just two weeks prior.
