The latest version of the iPhone had Apple fans turning out in droves as it was released around the world.
People queued overnight in their hundreds outside stores in London, Paris and Frankfurt as well as the US and Japan.
The devices popularity was shown with a record 600,000 pre-orders in a single day last week.
Buyers said there was a party atmosphere while waiting in line which was as much an attraction as being the first to own the phone.
In Tokyo more than 500 people braved dreadful weather some costumed in imitation of their object of desire.
An 18-year-old student, Akira Nakazawa, was at the head of the queue. He said: “I’ve been waiting for almost 33 straight hours, since two days ago from 10 pm on the 22nd. The hardest part was being under heavy rain through the day yesterday. I had to have two umbrellas to protect myself and my stuff.”
The phone has become Apple’s main growth driver, and is expected to soon become its biggest source of revenue.
Analysts expect Apple to ship more than three million a month in the battle for the hard-fought and fast-growing smartphone market.
