With the introduction of iOS 1, or iPhone OS 1, it was all about its UI. The OS was the core of the iPhone back then, and it made complete use of its 3.5-inch touchscreen display. It was fast, had great features like Google Maps, and it encompassed everything we loved from the iconic iPod Touch into a mobile device. Sure it had basic features and apps, and what you got with it you had to deal with because there was no App Store, but back then we had no idea what an App Store was.

iOS 2.0 – The App Store


iOS 2 brought with it the App Store, so the ability to download new content to your iPhone was a blessing in disguise. It was the introduction to the hub that we all use today, to download new games, new photography apps, and new ways to socialize. iOS 2.0 was the game changer in the industry as developers could now finally make their own visions a reality on a device.

The first ever iPhone with a Retina Display launched and along side it, iOS 4.0. The new OS came with over 100 new features and most of these were game changers. Folders, multitasking, FaceTime, spell check, and more. It was a great new OS to accompany a brand new iPhone that also packed new features.

Although it was not al fun and games, even though Game Centre launched with iOS 4.1, as the new iPhone was plagued with, what we knew back then as “Antennagate”. This was due to the iPhone 4’s poor placement of its antennas on the side of the device that interfered with your holding of the device and causing poor signal quality. Apple fixed these issues with a few iOS updates and at the same time released Game Centre, Airplay and personal 3G hotspots.

iOS 5 – Hello Siri

iOS 5 released alongside the iPhone 4S, this was the introduction of our favourite PA, Siri. As an iPhone 4S exclusive feature, Siri was highly sough after, so much so that hackers managed to port her to older devices and, made her run off of custom built servers.

Other than that, iOS 5 also came with an improved Notifications Centre, iMessage, Wireless activation, and iTunes sync over Wi-Fi. Apple also scrapped Mobile Me and introduced iCloud.
