Here's How Your iPhone Software Has Changed Every Year Since 2007 (AAPL)

Apple's operating system for iPhones, iOS, is about to enter its eighth version this fall.

iOS has come a long way since Apple showed off the first version over seven years ago.

Change may seem incremental year to year, but if you start from the beginning, you can see just how much better the iOS has gotten since version one.

2007: When Steve Jobs introduced the first iPhone, he didn't call the software iOS. Instead, it was OS X, the operating system for Macs that iOS is based on. The iOS name came later.

Here's the original home screen for the first version of iOS. These were the only apps you could use. There was no App Store for downloading new apps and games.

This is what the original iPod app looked like. Years later, Apple renamed the app to Music.
