Since Steve Jobs launched the first iPhone back in 2007, the Apple smartphone has become a worldwide cultural phenomenon.
As of July 2016 it was reported, by Statista, that global sales of iPhones have exceeded 1 billion units.
Now, on 7 September, we will see the launch of the eleventh generation handset - the iPhone 7- and if the leaks we’ve seen so far are anything to go on then the iPhone 7 will feature a design that’s similar to both the iPhone 6 and iPhone 6s.
But do you remember what the iPhone 1 looked like all those years ago?
iPhone 1 - November 2007
Now we might take touchscreen and internet at our fingertips for granted, but back in 2007, the iPhone 1 was groundbreaking.
Combining a touchscreen iPod, a mobile phone, and a mobile web browser with 320 x 480 pixel resolution and 8GB storage.
iPhone 3G - July 2008
Despite being the second generation iPhone, 2008 saw the launch of the iPhone 3G - which was all about connectivity (hence the moniker).
The new phone also supported the newly launched app store.
iPhone 3GS - June 2009
On the surface the 3GS didn't offer a massive step forward, but what it did have was faster performance and now a camera that could record video.
And it even had the primitive ancestors of Siri - voice control.
iPhone 4 - June 2010
If people had been underwhelmed by the offerings of the iPhone 3GS, then the iPhone 4 was a leap into the future.
The high-res retina display now had 640 x 960 pixels and a 5MP camera with HD video recording capabilities.
iPhone 4S - October 2011
As with the 3GS move, the 4S indicated that Apple wasn't making big changes but improvements to the previous device.
Inside was the massively improved A5 processor, and Siri - an exclusive 4S function.
iPhone 5 - September 2012
It was finally time for Apple to tip the screen-phone ratio.
Offering a much larger screen: little did we know how many smashed screens this would result in...
iPhone 5S/5C - September 2013
The launch of the iPhone 5S bought a larger battery, more power, better camera, fingerprint reader, and iOS 7 was finally here.
September also saw the introduction of the cheaper plastic-backed 5C model to compete with the influx of Androids on the market.
iPhone 6 - September 2014
Anyone who has held an iPhone 6 can testify that when Apple made the leap to the eighth generation, they decided to make everything just that bit bigger.
The screen is now 4.7 inches and boasts an impressive resolution of 1334 x 750.
iPhone 6S - September 2015
As with every other Apple 'S' product, the changes between the iPhone 6 and 6S were not drastic (although they did launch a rose gold version for the first time...)
iPhone SE - March 2016
Back to the smaller 4 inch screen, the iPhone SE also comes with a 12MP rear-facing camera, a 64GB storage option and iOS 9 software.
We can't wait to see what the iPhone 7 brings on 7 September.
