The newly released iPhone 5S is being offered for sale on eBay in the UK for as much as STG2000 ($A3418) by those anticipating enthusiastic fans will pay over the odds to get their hands on the device.
The wait for the new handset finally ended on Friday as thousands of people streamed through the doors of Apple stores around the country, many of them having camped out for days.
The 5S device, said to be twice as fast as its predecessor, is available in the UK through EE, O2, Three, Carphone Warehouse and Phones4u priced at STG549 (16GB), STG629 (32GB) and STG709 (64GB).
But with hundreds of listings on eBay for the device with fixed prices running into the thousands, it appears that those who have already bought it are hoping to cash in and make a hefty profit.
Some tech fans began queuing outside Apple's flagship store in London's Regent Street as early as Monday afternoon to buy Apple's latest model, which is equipped with a fingerprint scanner.

Noah Green, 17, was the first in the queue, and said he turned down offers of up to STG5000 ($A8547) for his prime spot but would have only considered giving up his place for STG10,000.
Emerging from the store 20 minutes after the doors opened to rapturous applause, the teen, clutching a limited edition gold device, said: "It's the best feeling in the world".
He said had only left his vigil to shower at a nearby gym since setting up camp outside the store.
