Since how long have you been using products of Apple, long enough I suppose. Have you ever wondered where it all came from or where it all started, and what journey the makers have been through to get you all the latest versions you are now using? If you are using iPhone and don’t know any history of iPhones iOS, then you have come to the right place. Let’s take a look at Apple’s mobile OS version’s history. Shall we?

WHEN DID IT ALL BEGIN?

Apple’s iPhone operating system is known as iOS. It was initially introduced on June 29, 2007, along with Apple’s first phone, the “iPhone.” For the first three years (2007-2009), it was known as “iPhone OS,” however, in 2010, it was renamed “iOS.”

WHAT IS iOS?

IOS is an operating system, and it’s the basic software that all devices come with in order to run and support other programmes. In simple words, iOS is to iPhones what Windows is to PC.

iOS differs from most other operating systems because it separates each programme in its own protective shell, preventing other applications from interfering with it.

Since 2019, the iPad has had its own operating system, known as iPadOS.

To identify iOS versions, Apple employs simple number modifications. The higher the number, the more recent the OS version.
