A Detailed iOS Version History

iOS Version History

This is a complete guide about Apple iOS mobile operating system version history.

In 2007, Apple revolutionized the mobile world by introducing the iPhone. At the time the Blackberry ruled the land of somewhat “primitive” smartphone devices. It never quite took off like its designers hoped, likely due to the cumbersome, compact keyboard that took up almost two-thirds of the face of the device.

The iPhone however came roaring into the market with a touchscreen that would permit users to operate all of the phone’s capabilities right from the screen rather than a tiny button keyboard.

To power the breakthrough device, Apple needed an operating system capable of supporting its new multi-touch interface. Steve Jobs insisted on building the operating system from the ground up, rather than relying on third-party technology. And what Apple put together would become the foundation that Apple would build upon for nearly a decade in a half.

The operating system was dubbed the iOS. And since 2007 it’s evolved into a powerhouse of a system, as Apple continuously stepped up the game releasing 12 subsequent releases (so far), continuously improving the interface and the phone’s vast set of features and capabilities.

Let’s take a trip back to 2007 when it all started, and take a journey through time with stops along the way in every version of iOS.

iOS Version History

iPhone OS 1, June 2007

The genesis of the iOS first surfaced in supporting the iPhone on June 29th, 2007. It did not have a moniker nor a version at the time of launch. The numbering schedule wouldn’t come into the picture until iOS 4.

Though primitive when compared to today’s iOS versions, back in 2007, this operating system was a groundbreaking achievement of technology whose impact on what followed cannot be overstated. It made significant progress in common areas of support for the multitouch screen, iTunes integration, mobile browsing with the Safari browser, and visual voicemail.

The iPhone OS 1 contained several apps preinstalled on the phone including a camera, mail, phone, photos, calendar, notes, the Safari web browser, and an iPod feature (which would later become video and music apps). Because Steve Jobs insisted on having the iPhone operating system be homegrown, what this early version of iOS did lack was the use and support of third party applications.

Several versions followed iPhone OS 1’s initial release, with version 1.1.5 being it’s last in July of 2008. As Apple moved on to new iOS systems, the support for the original iPhone OS was halted in 2010.

In 2007 and through 2008 the iPhone took off, becoming an unprecedented success, being adopted by the masses ravenous for this new, futuristic technology. In January 2009, Apple unveiled the iPhone 3G, and it coincided with iOS 2.0 (though at the time it was known as the iPhone OS 2.0).

The most significant of the changes that the iPhone OS 2 brought along with it was undoubtedly the introduction of the App Store. Now Apple was ready to support hundreds of third-party apps, with roughly 500 being included in the app store at the time of launch.

The second iPhone OS version had experienced 5 updates, which added hundreds of improvements and introduced features like walking directions and public transportation directions in its Maps app. Additionally, iPhone OS 2 introduced podcasting support.

Version 2.2.1 concluded the version releases for the iPhone OS 2, with the support for the system wrapping up in 2011.

iPhone OS 3, June 2009

When the iPhone 3GS made its debut in August of 2010, it came loaded with the next phase of iPhone OS systems. iPhone OS 3 added the ability of the camera app to record videos and supported new features like a Messages app with MMS support, copy & paste feature, and the Spotlight search.

This was also the first operating system that supported the iPad, the first generation of which was introduced in 2010 and was preloaded with version 3.2 of the iPhone OS. In August 2010, Apple released version 3.2.2, which would be the final iPhone OS 3 version released, until the support for it ended in 2012.

iOS 4, June 2010

In July of 2011, what is widely considered the first early contemporary version of the iOS was released. It also happened to be the first operating system to be dubbed “iOS”, replacing the iPhone OS moniker of the prior releases.

This one came loaded with many new features, most of which are a staple of modern-day iPhones. These included iBooks, Facetime, AirPrint, AirPlay, and Personal Hotspot. Also, it introduced the ability to organize applications into folders, creating a logical category split, and allowing users quicker access to more apps from the front-page screen.

What was abandoned in this iOS 4 version was the support for the original iPhone as well as the iPod touch (1st generation) product. After releasing version 4.3.5 in July 2011, Apple ceased further enhancements of iOS 4 and wrapped up support in 2013.

iOS 5, October 2011

The first iOS version to allow for the ability to activate the iPhone wirelessly came with iOS 5 in October 2011. This was Apple’s answer to the increased demand for wirelessness and cloud computing. This iOS also featured the ability to sync the phone with the iPhone via Wi-Fi connection rather than with a more traditional corded method.

iOS 5 was the first iOS version that could be updated over Wi-Fi without connecting your phone into a computer and sync it with iTunes.

This iOS version also marked the debut of current mainstay features like the Notification Center and the iMessage. With this iOS, Apple abandoned support for 2nd and 3rd generations of iPad touch, the 1st generation iPad, as well as the iPhone 3G.

After releasing version 5.1.1 in May 2012, Apple ended the support for iOS 5 in 2014.

iOS 6, September 2012

By September 2012, when iOS 6 entered the picture, the competition for Apple from Android smartphones was heating up, with Google pushing in on the Apple smartphone market. To remain differentiated, Apple abandoned the maps feature used in the earlier iOSs and pre-installed its own version of the Maps app. Unfortunately, the app was riddled with bugs, feature issues, and bad directions, causing a consumer backlash.

To add to the controversial iOS’s story, Apple CEO Tim Cook tried to get Scott Forstall, the development head for the iOS to publicly apologize for the shortcomings. When he refused, Cook fired the man involved with the iPhone product since the beginning to make a point.

However, iOS 6 did bring about some vital features to the iPhone product, not the least of which as the introduction of Siri. It also introduced the Apple Passbook (currently known as Wallet), as well as a do-not-disturb feature.

In February 2014, the final version of the iOS 6 was released (v. 6.1.6). Support for the operating system ceased in 2015.

iOS 7, September 2013

The iOS that followed faced another type of consumer backlash. This time it was due to the numerous operational changes. With the former head of iOS development no longer employed by Apple, the reigns were taken up by Jony Ive, who was Apple’s head of design. The iOS 7 overhauled a significant part of the interface in an attempt to make the iPhone product look and feel more modern.

However, it seemed as if there were too many changes all at once for most users who liked their older iPhone models. People complained about the difficulty of reading small, thin fonts as well as citing motion sickness being caused by the new animations.

With subsequent versions of the iOS 7, a lot of these troublesome complaints were pacified as Apple adapted the necessary changes. With all that, the iOS 7 would become the ground basis for the current iOSs. After version 7.1.2 in June 2014, Apple moved on past supporting this operating system in 2016.

iOS 8, September 2014

The iOS 8 returned with a renewed focus on delivering some significant new features like Apple Pay (a contactless payment method) as well as an Apple Music subscription service that arrived later in the iOS’s life (update version 8.4).

Working out the problems of the last two iOSs, Apple focused on improving the iCloud platform by adding multiple cloud-based apps like iCloud Photo and Music libraries. They also introduced iCloud Drive to compete with Dropbox. On top of that the HomeKit, Family Sharing, Handoff, and third-party keyboards were added to the mix.

While August 2015’s 8.4.1 version was iOS’s last, Apple continues to offer support for this operating system at this time.

iOS 9, September 2015

With September 2015’s iOS 9, Apple decided to address the observations that they got too focused on developing apps and were not focused enough on improving and beefing up the operating system itself. With iOS 9, they decided to do just that by making major improvements to stability, performance, speed, and responsiveness that plagued some of their older devices.

The iOS 9 served as a significant building block to the two subsequent iOS releases. However, it was not completely devoid of new features, introducing a low power mode battery saving option, a blue light-emitting level for dark rooms called the Night Shift, and introduced a beta program for some early adopters.

Version 9.3.5 was the final release for this iOS in August 2016, before Apple moved to a more robust iOS 10.

iOS 10, September 2016

Apple’s iOS became known as a “walled garden”. The idea was that being inside the iOS was great, but Apple’s hard restriction to its interface for third-party apps made it a tough place to get into. September 2016s iOS 10 had a more focused drive toward customization and interoperability.

Certain apps were now able to communicate and work with one another, even utilizing another app’s features without that app being opened to do so. More apps got integrated with iMessage and Siri as well.

Users were finally able to delete preinstalled apps, a feature that was well-received by consumers.

With this new iOS, came the drop of support for the 5 generation iPod touch, the iPhone 4S, the 1st generation iPad mini, as well as the iPad 2.

While Apple continues to support the iOS 10 products, the iOS 10 has not had an update since version 10.3.3 that came out in July 2017.

iOS 11, September 2017

Originally the iOS was developed with the iPhone in mind. Over time, it became the operating system for Apple’s other products like the iPod and the iPad. Even Apple TV and the Apple Watch are run on a modified version of it. But iOS 11 was the first time that the focus of development shifted to the iPad instead of the iPhone.

That is not to say that it was devoid of any new features for the iPhone however. When it was released in September 2017, it introduced features like AirPlay 2 and became capable of implementing augmented reality.

However, the major focus was on the iPad. As a lot of users have begun to use the iPad essentially in place of a PC, Apple felt they needed it to run with an operating system more akin to a desktop computer. Some of the changes included split-screen ability, file browser apps, drag, and drop capability, and multiple workspaces. It also supported handwriting and notation with the Apple Pencil.

The most current version of the iOS 11 is 11.4, which was released in May of 2018. Apple continues to support this iOS. It did however signal the support drop for the iPhone 5 and 5C, as well as iPad 3 and 4 models.

iOS 12, September 2018

Nothing overly dramatic changed in iOS 12 when it came out in September 2018. There were new features and enhancements added, but they were not as extensive as in some of the previous iOS systems.

This iOS was focused on improving several features on iPhones and enhancing the user experience. The main improvements were to Siri, as the addition of multi-step actions and Siri shortcuts. Improved augmented reality features with ARKit 2, as well as providing monitoring features for users (especially parents) to be able to control their devices with the use of Screen Time.

This iOS is at version 12.3.2 released in June 2019, with Apple continuing to support the product at this time.

iOS 13, September 2019

iOS 13 moved away from supporting the iPad with a renewed focus on the iPhone product. That is because iPad now had its own iOS to run (the iPadOS) which while being based on iOS 13, was geared to support iPad specific features. The idea was to focus the operating systems to perform more ideally for the iPhone, and this most recent and current iteration focused on updating some of the core iPhone features.

Among the updates were improvements to using Face ID (to unlock phones) faster, quicker app launches, and a fresh face on some of the mainstay features of the iPhone including the Safari browser, Mail, Reminders, and Notes.

This version introduced new privacy and security features, improved Siri’s voice, Sign In with Apple, the Look Around feature for Apple Maps (comparable to Google’s Street View), added Portrait Lighting options, and introduced the most notable new feature of a system spanning Dark Mode. Dark mode changed the interface color to avoid user eye strain when using the iPhone in a dark environment.

iOS 13 was released in September 2019, with the current 13.3.1 version being unveiled in January of 2020. The iOS also featured a support drop for 6th Generation iPod touch, as well as the iPhone 5S and the iPhone 6.
