Apple’s iOS through the years

When Steve Jobs demonstrated the first iPhone at Macworld in January 2007, he famously stated that smartphones at the time had baby software while referring to WAP as the baby internet.

While that may have been true, its easy to look back today and highlight everything that iOS didnt have. You see, when it came to operating system development, Steve Jobs adamantly believed that you had to start humbly, focusing on the simple elements such as what a button would look like. Then build upon the solid foundation.

If we included every iOS feature you’d be here all week and probably bored to death, so we’ll only focus on the major stuff.


iPhone OS 1

Announced: January 9, 2007

Released: June 29, 2007

Apples original iPhone OS was a seminal achievement. Running a modified version of OS X, the Apples Mac Operating System, Apple’s engineers, had a number challenges ahead. Not only did the code base have to be reduced to a tenth of its size, during development engineers had to simulate chip speeds, and the impact on battery life as the physical chips would not be manufactured until much later into the development cycle.

Steve received his first of many cheers from the crowd early in the iPhone announcement playing the audience:


Today, were introducing three revolutionary products of this class.


The first one: is a widescreen iPod with touch controls.


The second: is a revolutionary mobile phone.


And the third is a breakthrough Internet communications device.


So, three things: a widescreen iPod with touch controls; a revolutionary mobile phone; and a breakthrough Internet communications device.


An iPod, a phone, and an Internet communicator. An iPod, a phone Are you getting it?


These are not three separate devices, this is one device, and we are calling it iPhone.

Initially Apple used the three above associations to group iPhone OS features and to better resonate with consumers, after all, who on the planet didnt know what an iPod was.

The non-editable dock contained;

Phone – including Visual VoiceMail
Mail – HTML e-mail
Safari – web browser
iPod – music/video player

While on its single, non-editable Home screen the following built-in applications were provided;

Text Calendar Photos Camera
YouTube Stocks Maps Weather
Clock Calculator Notes Settings

Apple and Google werent competitors yet in this space, so the Apple Maps and YouTube applications utilized Googles back-end services. Meanwhile Yahoo provided the back-end service for the Weather app.

Steve Jobs was also an advocate of Skeuomorphism interface design, with icons mimicking real-life objects and materials within the iPhones OS. This trend would peak with iPad apps containing leather stitching and paper textures. iOS 7 would later banish this to the history books.


Skeuomorphism at its worse
Things improved from iOS 7 onwards

iPhone OS 1 introduced many of the concepts that were familiar with today including slide to unlock, multi-touch including pinch to zoom and badge notifications. What was missing? Famously, Text didnt support the widely adopted MMS standard, you couldn’t search in the Contacts app, while Copy & Paste including other features such as wallpapers would be added in future iOS releases.

Additionally, the majority of your content was synced via physically connecting to a PC or Mac via iTunes.
