iOS 7 teaser (iPhone 5s ad 009)

The iPhone has come a long way since it was first introduced in 2007. Now generating more than 30 million sales per quarter, the popular handset has become a large part (over half) of Apple’s business.

With that in mind, we found this infographic of how the iPhone has grown over the years very interesting. Not only does it show the hardware and software changes it’s undergone, but also its increase in sales…

Here’s the infographic by Top Tien Mobiel (via The Loop):

While overall iPhone sales aren’t increasing from quarter to quarter as rapidly as they were say, 2-3 years ago, they’re still very impressive. Apple’s opening 5s/5c weekend was nearly double that of the iPhone 5.

I also find the hardware and software changes from year-to-year interesting. Note how different the iPhone 3G and 4 appear—just 1 generation apart. And then of course there’s the iPhone 5c and iOS 7.

It kind of makes you wonder how next year’s iPhone will evolve from the current models. Recent reports claim the handset is set to receive a big makeover with larger screen sizes and possibly curved displays.
