Apple Inc. provides updates to the iOS operating system for the iPhone, iPad, and iPod Touch through iTunes, and since iOS 5.0, also through over-the-air software updates. With the June 6, 2011 announcement of iOS 5.0, a USB connection to iTunes is no longer needed to activate iOS devices; data synchronization can happen automatically and wirelessly through Apple's iCloud service. The most recent update, iOS 8.1.2, was released on December 9, 2014; 48 days ago (2014-12-09).
Apple's iOS did not have an official name until the release of the iPhone software development kit (iPhone SDK) on March 6, 2008. Before then, Apple marketing literature simply stated that their iPhone runs a version of OS X, a reference to iOS' parent operating system. When introduced, it was named iPhone OS. It was renamed iOS on June 7, 2010, as the iPhone was no longer the only device to run iOS. Apple licensed the "iOS" trademark from Cisco.
On June 29, 2007, Apple released the first version of what became iOS – concurrently with the first iPhone. The final 1.x series release was 1.1.5, released shortly after version 2.0.
July 11, 2008 saw the public release of iPhone OS 2.0, with upgrades through version 2.2.1 made available.
June 17, 2009 was the release date for iPhone OS 3.0. It was updated through (and including) version 3.1.3 (release date February 2, 2010). The first generation iPod Touch and iPhone have iPhone OS 3.1.3 as their newest available version. The iPad was introduced with iPhone OS 3.2, later updated to 3.2.2. 3.2.x versions of iPhone OS were made specifically for the iPad.
On June 21, 2010, iOS 4.0 was released to the public and was made available only to the iPod Touch and iPhone. iOS 4.0 was announced to have over 1500 new APIs for developers, with the highly anticipated multitasking feature. The iPod Touch (2nd generation) and iPhone 3G have iOS 4.2.1 as the final version available. Nevertheless, many features are not available for the iPhone 3G or iPod Touch (2nd generation), such as multitasking and home screen backgrounds. iOS 4.2 is the first version to bring major feature parity to the iPhone and iPad. The release of the CDMA iPhone for Verizon Wireless saw a branching of iOS. The 4.2 version sequence continued for the CDMA phone while 4.3 was released for all other products.
iOS 5 had only three minor additions, 5.0.1, 5.1, and 5.1.1, which were all provided as OTA and iTunes software updates.
Apple concurrently provides the same version of iOS for the comparable model of iPhone and iPod Touch, usually devices released in the same calendar year. iPhone users receive all software updates for free, while iPod Touch users paid for the 2.0 and 3.0 major software updates. As of iOS 4.0, Apple no longer charges money for iPod Touch updates.
As of October 23, 2011, two versions of iOS were never released. iPhone OS 1.2, which after the first beta was replaced by a 2.0 version number; the second beta was called 2.0 beta 2 instead of 1.2 beta 2. The other was iOS 4.2, replaced with 4.2.1 due to a Wi-Fi bug in 4.2 beta 3, causing Apple to release 2 golden masters (4.2 GM and 4.2.1 GM). One version of iOS was pulled back by Apple after being released. iOS 8.0.1 was pulled back by Apple because cellular service and Touch ID were disabled on iPhone 6 and iPhone 6 Plus.
The current version is iOS 8.1.2 which addresses an issue where ringtones purchased from the iTunes Store may have been removed from the device.
First iteration of Apple's touch-centric mobile operating system. No official name given on its initial release; Apple marketing literature simply stating the iPhone runs a version of Apple's desktop operating system, OS X. On March 6, 2008, with the release of the iPhone software development kit (iPhone SDK), Apple named it iPhone OS (they went on to rename it "iOS" on June 7, 2010).

Apple announced iOS 8 on June 2, 2014 at its annual Apple Worldwide Developers Conference (WWDC) event, with release announced for sometime in Fall (Northern Hemisphere) or Spring (Southern Hemisphere) 2014. At their iPhone event on September 9, 2014, Apple announced the full release of iOS 8 for September 17, 2014, while also unveiling the iPhone 6 and iPhone 6 Plus. With this release, Apple resumed the cycle of dropping support for older devices, specifically the iPhone 4. Supported devices on this release include the iPhone 4S onwards, iPod Touch (5th generation), the iPad 2 onwards, and the iPad Mini (1st generation) onwards. The iPad 2 is also the first iOS device to support 5 major releases of iOS, supporting iOS 4, 5, 6, 7, and 8. This is the greatest amount of major iOS releases a single iOS device has supported, surpassing the iPhone 3GS, 4, 4S, and iPad (3rd generation) which all support 4 major releases (iPhone OS 3, iOS 4, 5, and 6; iOS 4, 5, 6, and 7; and iOS 5, 6, 7, and 8 respectively). However, iOS 8 has limited support for this device's predecessor and the iPhone 4S. The current version is iOS 8.1.2 which addresses an issue where ringtones purchased might have been removed from the device. The latest beta version is iOS 8.2 Beta 4. The iPhone 4S and iPad 2 will be stuck with iOS 8 after iOS 9 is released.

The Alarm feature of the built in Clock app in the iPhone and iPod Touch has been plagued by major bugs in all versions of iOS 4. The first bug noticed was the "DST bug" which was first seen when some countries switched to/from daylight saving time from/to standard time in October/November 2010. It caused recurring alarms to start going off an hour too early or late. Apple promised the bug would be fixed in iOS 4.2 but according to some reports it still exists even in iOS 4.3.1.
The second alarm clock bug discovered was the "New Year's Day bug" which showed up on January 1, 2011 as well as January 1, 2012. It caused non-recurring alarms not to go off at all. However two days after each New Year's Day, on January 3, 2011, they "magically" started working again. This bug was seemingly fixed in iOS 4.3.
Apple confirmed that several battery life bugs were negatively affecting battery life in iOS 5. They attempted to fix these bugs with iOS 5.0.1 and 5.1 but the problem still remained. Finally, these bugs were fixed in iOS 5.1.1.
The launch of the iOS 5 update on October 12, 2011 (including iOS 5.0.1 released on November 10, 2011) led many users to report a major bug causing the device to lose Wi-Fi access. This problem has supposedly been fixed with the release of iOS 5.1.1
Some users of the iPhone 4S and iPad (Wi-Fi + Cellular) reported issues with the SIM card in iOS 5.0, and even though Apple attempted to fix these issues in version 5.0.1 build 9A406 (for iPhone 4S only), they still remained.
Some users of the iPhone 4 and iPhone 4S reported issues with having echo problems during phone call in the initial release of iOS 5, which causes echoes to appear randomly during phone calls made through earbuds. The other party in the call is generally unable to hear the conversation due to this problem. The owners reported a "fix" that is to switch to speaker mode when echo happens then switch back (turn speaker off), which would get rid of the echo temporarily, but it might happen again within the same phone call. It is unclear that whether Apple attempted to fix this issue in version 5.0.1, but for many users this problem still remains after updating to 5.0.1. It appears that the new noise-cancelling microphone/technology might be the reason behind this bug. Apple has since released version 5.1.1 in an attempt to fix the problem.
Apple has admitted that there were several bugs in the mapping app on iOS 6, with cities in the wrong location, some places being missed off altogether, some places misnamed and places of interest in the sea.
Many users report a problem with Bluetooth audio streaming to a range of compatible devices. The sound cuts out every now and then for no apparent reason. As of October 2012[update], no solution has been provided by Apple.
Location-based reminders do not work for iPads, even though they were promised to work on cellular enabled devices.
A lot of users reporting problems with the iPhone 5 not reconnecting to the cellular network, when having lost connection for more than 5 minutes and staying at "No Service". As of December 2012[update], no solution has been provided by Apple and the problem was not solved with the 6.0.1 iOS release.
From iOS 6.1, new major bugs have been identified. The first was addressed when iOS 6.1.1 was released that "fixes an issue that could impact cellular performance and reliability for iPhone 4S".
Do Not Disturb
Many iPhone users experienced a bug with the Do Not Disturb feature when the calendar changed from 2012 to 2013. The feature would be left on past the scheduled time set by the user, allowing texts, notifications, and alarm settings to be missed. The bug was caused by a difference in formatting in the ISO calendar system versus the Gregorian calendar system. Apple did not offer a quick software update for the bug, instead saying that the bug would fix itself on January 7, 2013.
Another bug causes issues when iOS devices connect to a Microsoft Exchange server to retrieve email, resulting in message "mailbox server resources are consumed, log growth becomes excessive, memory and CPU use may increase significantly, and server performance is affected". Microsoft have suggested several workarounds, and Apple responded with a KnowledgeBase article describing the cause of the bug and a suggested temporary workaround, promising a fix in the near future, which was then fixed with release of iOS 6.1.2.
Lockscreen bypass code
On iPhones, another bug found in 6.1 allowing bypassing the lock screen's passcode to temporarily gain full access to the Phone app, by performing a specific sequence of actions on the phone that remained unfixed, with Apple acknowledging the bug and then addressed with release of iOS 6.1.3.
Audio profile speakerphone
iPhone 5 users experienced dropped calls during the release of iOS 6.1.3 when there was an issue with the audio microphone profile. This also caused issues with many voice-over commands, including Siri, to get different results than expected or to fail easily. Apple fixed this bug with the release of iOS 6.1.4 to update the audio speaker profile so users would get better results.
Shortly when Apple released iOS 7, the new software unfortunately left the iPod Touch (4th generation) along with the iPhone 3GS. However, a FaceTime issue occurred in iOS 7.0.3 when video calls were failing for users while developers on the iPod Touch (4th generation) addressed this same issue, while no longer supported and stuck on iOS 6.1.3. Apple then fixed this bug with the release of iOS 6.1.5 for the iPod Touch (4th generation) on November 14, 2013, along with iOS 7.0.4 for iOS 7 devices for the same purpose. iOS 7.0.4 included bug fixes that occurred during the release of iOS 7 whereas iOS 6.1.5 did not include the bug improvements that appeared on iOS 6 when Apple did not realize, noticeably since iOS 5, that the echo bug has still occurred. For example, during a FaceTime call, echoes occur when a person tries to speak to the other person that he or she's talking to. Because of this, the sound takes longer for the person to hear than the other person speaking.
An attacker can collect or modify data in sessions protected by SSL/TLS protocols. This same bug was also reported on iOS 7.0.4 and iOS 7.0.5 for the iPhone 5C & 5S. For the iPhone 3GS and the iPod Touch 4th generation, iOS 6.1.6 was released to fix this issue since they are no longer supported. (see iOS 7.x)
In iOS 7, users that were running iPhone 4 to iPhone 5, iPad 2, 3rd, and 4th generations, first-generation iPad mini, and iPod Touch (5th generation) have developed bugs that were previously retained since iOS 6. One example is the SSL/TLS protocol when the secure transport failed to verify certification authenticity (fixed in iOS 7.0.6). This caused the iPhone 3GS (initially ended with iOS 6.1.3) and the iPod Touch 4th generation (initially ended with iOS 6.1.5) to advance one update to iOS 6.1.6.
Passcode screen bypass bugs
People are able to bypass the "Enter Passcode" screen. This flaw was discovered within hours of it becoming publicly available. This is only able to be done on iPhone 5 and earlier while the iPhone 5C and iPhone 5S are safe from this bug. This is caused by the ability to use the control center via the lock screen and clicking on the camera or timer buttons. This feature is able to be turned off in the Settings app.
Users complained about dizziness and vertigo-like symptoms when using this operating system because of parallax motion effects. In iOS 7.1, a new function in the Settings app called "Reduce Motion" was introduced to reduce the motion of the user interface and disable the parallax effects.
Creation of CardDAV Accounts not working
Creating a CardDAV Account contains a bug that needs manual fixing of the CardDAV-Server-URL.
Battery drain problems
In iOS 7.1, battery life is reduced on an average 1% every 10 minutes,especially when the device is in sleep mode.
Issues with video-calling and connection errors. This was fixed in iOS 7.0.4. (See iOS 6.x)
Safari ignores local domain
Local domain names can no longer be resolved in Safari. This breaks short names on the local network, e.g. 'nas' for nas.<ourdomain>.
Home screen crashes
Users have reported various crashes of the home screen, the core service that renders the home screen icons, Notification Center, Control Center, Siri and the lockscreen.
Secure transport failed to validate the authenticity of connection. This issue was addressed by restoring missing validation steps. This may cause an attacker with a privileged network position to capture or modify data in sessions protected by SSL/TLS. This issue was addressed by the release of iOS 7.0.6.
Battery Indicator stuck until restart
iPhone 4S users report experiencing problems with the battery indicator; the indicator will freeze at the same value until the iPhone is restarted again.
Wi-Fi and Bluetooth
iPhone 4S users are reporting that after the update to iOS 7 their Wi-Fi and Bluetooth cannot be activated.
Phone and FaceTime History
In iOS 7.1.1, particularly on iPhone 5, the recent history data in both these applications cannot be deleted. (We wonder why.)
When using earphones on iOS 7.1.1 on iPhone 5, the ringer for any incoming alert (phone, messages etc.) only sounds on the phone speaker and not in the earpiece of the earphone. When you are in a crowded place, and vibrating phone does not suffice, the ringer will fail as well, one will not hear anything in the earphone.
In iOS 7.1.1 on iPhone 5, when users are listening to music via an auxiliary cable, the music continues to play after the cable has been unplugged. Previously, the music would pause.
The weather application displays the closest city of the current location instead of actual city of the current location. This may be an issue that Yahoo! might have not yet resolved.
In iOS 7.1, Touch ID was not functioning on the iPhone 5S. The problem cannot be resolved by turning Touch ID on and off in the "Fingerprint and Passcode" menu, restarting, resetting, or restoring the device using iTunes. This problem was similar to the iOS 8.0.1 release, which crippled iPhone 6 and iPhone 6 Plus of both cellular and Touch ID.
Shortly after the release of iOS 8, Apple released a statement pointing out that a bug had been found in the operating system which prevented HealthKit-compatible being released alongside iOS 8. Apps already released that included Healthkit functionality were withdrawn from the App Store. iOS 8.0.1 included a fix for this issue.
iPhone 6 and iPhone 6 Plus users who updated to iOS 8.0.1 wirelessly had cellular service of their iPhones disabled due to a software issue. Over-the-Air downloads of iOS 8.0.1 were stopped within an hour of the release of the software, but many early adopters had been affected. This issue was fixed at the release of iOS 8.0.2 a day later.

This issue was fixed at the release of iOS 8.0.2 a day later.
Many users of older generation devices such as the iPhone 4s and the iPad 2 reported performance issues with iOS 8.
Several issues with the new Keyboard API in iOS 8 were reported, including problems with custom keyboards crashing or not appearing, or being replaced with the default keyboard.
