Apple fans may have a good reason for worrying whether they'll be able to get the latest iphone.
9to5Mac and AllThingsD cite sources from U.S. carriers, reporting that the stock of the new iphone 5s will be limited when the device launches on Friday.
That's when the 5s goes on sale in 11 countries, including the United States, Canada, China, Australia, and Japan.
In China, where people could pre-order the device starting on Tuesday, news outlets report the gold models are already sold-out before it's even available for sale.
Gold and silver models will be harder to get, potentially leaving the grey models on shelves.
