Now that the iPhone 5 has been out for a few months, rumors and even leaked photos have surfaced online of the upcoming iPhone 5S.

According to report of 9to5Mac, Apple would launch two iPhones in the market- one with low-end features and cheaper price tag, and another phone with high-end features and higher price tag.

The need for the company to diversify its offerings was underlined yesterday by a report which showed that the iPhone is losing its appeal among well-heeled Asian customers.

French news blog nowhereelse.fr - a publisher of credible Apple leaks in the past - has posted photos it claimed to be speaker components of two forthcoming iPhones. The photos are said to have been taken by someone working in Apply, the French blog reported.

The rather fuzzy images purport to show the block speaker parts which will be used on the iPhone 5S and iPhone 6.

It is speculated that this could actually be designed for the as-yet hypothetical 4.8in iPhone, an iPhone Mini or a possible budget iPhone.

The French website is also reporting that the unnamed Apply source is pinning the release of the iPhone 5S sometime between March and July this year.

Meanwhile, the alleged time frame for the second iPhonemodel, rumored to be called the iPhone 6, is closer to the end of the year. Apple has not spoken about these rumors and has yet to respond to CNET's request for comment, but we'll post new information if we learn more.

Apple's CEO Tim Cook has discarded rumors of a potential iPhone 5S by saying that "the supply chain is very complex and we have multiple sources for things."

" Yields can vary, supplier performance can vary. There is an inordinate long list of things that can make any single data point not a great proxy for what is going on," he added.
