IOS 1 (IPHONE OS 1)
The brainchild of Steve Jobs introduced the idea that an iPod, camera, phone and internet device
could be compacted inside a device that fits in your pocket. At that time, iPhone was the actual
star and other than the technological geeks, no one was really interested in any information about
the operating system which made those phones work flawlessly.
iPhone OS 1, as it was named, was so special among the customers as it was designed for multi-
touch operation and a 3.5" capacitive touchscreen, which made it quick and responsive than any
other present in the market then. While comparing it with the consecutive versions of iOS, this
version lacked huge including support for native, third-party apps. But at the time of its launch,
the phone and iOS 1 created a massive buzz among the elites and technologically inclined lot.

IOS 2 (IPHONE OS 2)
iPhone OS 2 released a year after, on July 2008
created a major breakthrough by adding App store,
which allowed the support of native, third- party
apps. More than 500 third-party apps were added
on App store during its launch, along with built-in
3G and GPS technology. This gave smartphone
market the capacity to think limitless, which was
visible from Google's move just after a month of
IOS 2 launch- android released Android
Market, an older version of Play Store.

IOS 3 (IPHONE OS 3)
On June 2009, the next upgrade - iPhone OS 3-was not about any dramatic inventions or
transformations, but they focused on fine-tuning the already developed programs. Jobs elevated
the whole iPhone using to the next level by adding push notifications for third-party apps,
parental controls, tap to focus in the camera, in-app purchases and subscription models,
universal search with spotlight, and cut, copy, paste for the touchscreen age. Next January,
iPad was launched with an updated version of IOS 3 tailor-made just for the new model.
iTunes was also upgraded by adding options to buy movies, TV shows and books from iPhone
or iPod touch.You'll be able to use MMS on your iPhone 3G (yes, 1st gen iPhones will not get
the fortune of using MMS due to the use of a different cell radio). The new Messages
application will be taking the place of the SMS app and will allow you to send voice memos
and pictures to your friends.
Allows iPhone apps the ability to find other iPhone users over WiFi or Bluetooth. This can be
useful for anything from gaming to sharing data.

IOS 4 (IPHONE OS 4)
Multitasking was the word of Apple in June 2010, when they
introduced iOS 4 enabling the user to switch between the
apps in a flash with a double press on the home button. The
feature loaded update had the name iOS given to it, leaving
behind the word "phone" from the name of the operating
system indicating its compatibility with iPhones, iPods and
iPads. Face Time, multitasking, iBooks, organizing apps into
folders, Personal Hotspot, AirPlay and AirPrint, some of the
current popular OS apps were introduced then.

IOS 5 (IPHONE OS 5)
With the launch of iOS 5 in 2011, Apple was beginning an era of virtual assistants. Yes, Siri was
added to iPhone in this version and the whole world went crazy behind this possibility of having a
virtual assistant inside your phone, that will actually obey your tasks and even tell you jokes.
Apple was also getting ready to create new wave enemies in future like Whatsapp, by introducing
iMessage and iCloud.
"iOS 5 has some great new features, such as Notification Center, iMessage and Newsstand and we
can't wait to see what our developers do with its 1,500 new APIs," said Steve Jobs, Apple's CEO.
"Perhaps iOS 5's paramount feature is that it's built to seamlessly work with iCloud in the Post
PC revolution that Apple is leading."
Additional new features in iOS 5 include:-
- Mail enhancements which include the ability to compose messages using draggable addresses, and
a new formatting bar with bold, italics, underline and indention controls;
- AirPlay® Mirroring to wirelessly display everything you do on your iPad 2 right on your HDTV
through Apple TV®; and a system-wide split keyboard to make it even easier to type on your iPad.

IOS 6 (IPHONE OS 6)
iOS 6, launched in 2012 witnessed a major fail- the introduction of Apple maps as a counter-
attack on popular google maps.It is marked as a mediocre step from the stellar Apple.Inc, as it
didn't make any noise even among Apple's most loyal customers or even inside Apple family.
They also removed Youtube from the pre-installed set of apps. Some other added features include
a tighter integration with Facebook, a new Passbook app and the iCloud allowing shared photo
streams.
Unlike past iOS versions, two apps that were removed as part of iOS 6 were Google Maps and
YouTube. These apps can be downloaded for free in the App Store.
The all-new Maps application uses a different engine. A completely brand new redesigned Maps
app was released made by Apple Inc., with help from TomTom, Google Maps was removed.
Siri - Now understands more languages, works in more countries, can respond to sports scores,
movies, etc. Siri is also compatible with the new iPad and 5th gen iPod Touch.
Facebook - Fully integrated into iOS, now you can do most features like with Twitter.

IOS 7 (IPHONE OS 7)
The world shouted "flat is beautiful" as the new iPhone was released with an updated iOS 7. The
features included Contol Centre which meant quick settings, iTunes radio service, multitasking for
all the apps, updated versions of Safari and Siri, and finally Airdrop was introduced which enabled
easy connectivity and file transfer to other iPhones. iOS 7 was designed to be compatible with all
existing iOS 6 apps, and user testing has found this to generally be true. If you rely on a specific
"mission critical" app, it would still be prudent to make sure that that app runs before upgrading.
As part of its announcement of launch weekend sales of nine million units combined for the
iPhone 5s and iPhone 5c, Apple also revealed that there were over 200 million devices running
iOS 7 less than five days after the launch of the new operating system, making it the fastest
software upgrade in history.Beyond the aesthetic redesign, iOS 7 also contains numerous tweaks
and features that streamline user configuration. Multitasking has been vastly overhauled for iOS 7,
offering a new cards look for apps that allows for easier quitting by swiping up out of a preview
screen, while also intelligently scheduling updates for apps that pull data.

IOS 8 (IPHONE OS 8)
Again, in September 2014 Apple was in the mode of fine-tuning the existing features. Firstly,
they brought together their desktops and mobile phones closer by providing a continuity concept
enabling the user to send, edit and receive messages or answer phone calls on both phones and
Mac. They opened up the platform wider by allowing third-party widgets and keyboards for users
to customize their iPhone and introducing a successful and secured payment option- Apple pay.

with its equivalents. Apps like notes, transit, Apple music and news
got a major fix, and 3D touch was introduced.iOS 9's biggest focus
is on intelligence and proactivity, allowing iOS devices to learn user
habits and act on that information, opening up apps before we need
them, making recommendations on places we might like, and guiding
us through our daily lives to make sure we're where we need to be
at the right time.

novel concept for drag and drop interactions and simpler multitasking.
Previous versions of iOS could run both 32-bit and 64-bit apps, but iOS 11 can only run 64-bit
apps. This means some older apps will no longer open once you upgrade to iOS 11. However,
most app developers have already updated (or will update) their apps to 64-bit versions, so this
will only affect a small percentage of apps.iOS 11 includes numerous tweaks, improvements, and
