IOS version history

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 major update, iOS 7, sees the addition of many new features, including a new flat theme, AirDrop support, and Control Center.

Overview
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 iPhone was no longer the only device to run iOS. Apple licensed the "iOS" trademark from Cisco.

Versions
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 before 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, a version 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.

On June 6, 2011, Apple previewed iOS 5, Apple TV 4.4 beta and the iOS SDK 5 beta along with iCloud beta among other products. This update introduced iMessage chat between devices running iOS 5, a new notification system, Newsstand subscriptions, Twitter integrated into iOS, Reminders app, Enhancements to AirPlay, full integration with iCloud and over 200 new features. iOS 5.0 supports all iPad models, iPhone 3GS, iPhone 4 GSM & CDMA, and the iPod Touch (3rd & 4th generation).

iOS 5 had only three minor additions, 5.0.1, 5.1, and 5.1.1, which were all provided as an OTA software update.

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 for iPod Touch updates.

As of October 23, 2011, two versions of iOS were never released. iOS 1.2, which after the first beta was replaced by a 2.0 version number; the second beta was called 2.0b2 instead of 1.2b2. 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 more golden masters (4.2 GM and 4.2.1 GM).

iPhone OS 1.x
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).

Supported devices include the iPhone 3GS and later; the iPod Touch (4th generation) and later; and the iPad 2 and later.

On September 12, 2012 at San Francisco's Yerba Buena Center for the Arts, among other items unveiled, Apple announced three iOS-related items: the next generation iPhone 5, the redesigned iPod Touch (fifth generation), and the announcement of the release of iOS 6.0 the following week.

iOS 4.x
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.
 * Alarm clock bugs

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.

iOS 5.x
Apple has confirmed that several battery life bugs are negatively affecting battery life in iOS 5. They attempted to fix these bugs with iOS 5.0.1 but the problem still remained.
 * Battery, Wi-Fi, SIM card, and echo bugs

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 reported issues with the SIM card in the initial release of iOS 5, and even though Apple attempted to fix these issues in version 5.0.1 build 9A406 (for iPhone 4S only), they still remain.

Some users of the iPhone 4/4S 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 earphones. 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.

iOS 6.x

 * Maps, Bluetooth, location-based Reminders, Do Not Disturb, Microsoft Exchange, lockscreen bypass, Audio Profile Speakerphone, and FaceTime bugs

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. , 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. , no solution has been provided by Apple and the problem was not solved with the 6.0.1 iOS release.

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.

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".

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.

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.

iPhone 5 users experienced dropped calls during the release of iOS 6.1.3 when there was an issue with the audio speaker profile. This also caused issues with many voice-over commands, including Siri, to get different results than expected or 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 6.1.3 when video calls were failing for some users on the iPod Touch 4th generation. 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.

iOS 7.x
Lockscreen bypass bugs

People are able to bypass the lockscreen. This flaw was discovered within hours of it becoming publicly available. The exploit is only able to be done on the iPhone 4S and 5 with the 5S and 5C safe from this bug. The access is caused by the ability to use the control center via the lock screen, this feature is able to be turned off.
