Carrier O2 said on Tuesday its website had been unable to cope with demand, which peaked at 13,000 per second. It later said it had sold out.
Carphone Warehouse said the level of interest was 10 times that for the original iPhone last year. Neither company would give sales figures.
Both O2 and Carphone Warehouse said they had separate stocks of iPhones to sell in their stores from Friday morning when the phone will be launched in 22 countries. The phone is expected to go on sale in 70 countries by the end of the year.
