The new iPhone models have gone on sale, with eager shoppers flooding into Apple's flagship stores.
The three models are on sale in the US, Australia, China, Canada, France, Germany, Singapore and UK but not yet in New Zealand.
In Britain, new models of the £549 ($1050) iPhone 5S appear on eBay for as much as £2000, as stores run out of the hotly anticipated phone.
Hundreds of people took to Twitter to say many stores had ran out of the new devices, while Apple's online store pushed back its dispatch date for new phones to next month, without giving any specific dates.
