The iPhone - the device that redefined the mobile phone and made Apple the world's most valuable company - was unveiled on this day 10 years ago.
More than one billion iPhones have been sold since Steve Jobs took to a stage at Macworld in San Francisco promising "an iPod, a phone and an internet communicator" - before revealing one device that performed all three functions.
iPhone fever has sent Apple's value soaring to £515bn - despite the first year of falling iPhone sales in 2016.
There have been 11 new versions of the phone since that launch, with some controversial redesigns including different-sized models, changes to screen sizes and disappearing headphone jacks.
The device also led to the launch of the App Store in 2008 - and the creation of a new digital industry, making fortunes for the inventors of apps such as Angry Birds, Uber and WhatsApp.
Other innovations include the Siri voice-activated personal assistant, the use of Touch ID and a powerful 64-bit processor.
The phone has been such a hit that the phone alone has generated more cash than the product ranges of Microsoft and Google.
The next version of the phone - expected to be unveiled in September - has been rumoured to feature a larger screen that covers most of the front of the device.
