Technology enthusiasts have paid their "last tribute" to the late Steve Jobs as they queued - some for days - to get the new iPhone.
Crowds of people flocked to Apple stores around the country to get the must-have smartphone in the wake of the Apple founder's death last week after battling pancreatic cancer.
Hundreds of technophiles were cheered and clapped into Apple's London Covent Garden store as the doors were flung open at 8am.
The launch of the iPhone 4S came during a torrid week for rival BlackBerry, which sparked widespread anger following a technical failure which left millions of its customers unable to access email or internet services for more than three days.
Duncan Hoare, 42, from Hampstead, was first in the queue and had been camping out since Tuesday afternoon.
Mr Hoare said Mr Jobs' death was "tragic", adding: "He will be a huge loss to the world. I would have come anyway and I would have bought the phone anyway but I think there's a lot of thoughts here for him."
Matthew Kelly, 19, from South Wales, had been queuing since Thursday. He said: "BlackBerry epically failed. You could not send messages, you could not connect to the internet, you couldn't get emails or anything."
The iPhone 4S, described by its makers as "the best iPhone ever", has already proved itself to be more popular before its release than any other Apple product, with pre-orders topping one million in a single day.
New features include an advanced camera; Siri, a so-called intelligent assistant that "helps you get things done just by asking"; and iCloud, a service which synchronises content across multiple devices.
Every customer who buys the phone at one of the UK's 33 Apple shops on Friday will be offered a free set-up service to help them customise their phone and get going on email.
