With two weeks to go until Apple's scheduled Sept. 10 event, fresh rumors about what the company's next iPhone will look like and do are emerging daily.
A top-of-the-line version, which would be called 5S if Apple follows previous naming conventions, is also reportedly in the works. It's likely to have a processor that's slightly faster and less draining on the battery.
The newest rumors suggest that the 5S will come in gray/silver, gold, black and white.
Among other features, the 5S is to have an improved camera and larger storage. The camera, with an f-stop of 2.0, would have a wider aperture than its predecessors, allowing for sharpers images in low lighting.
The home button on the 5S is expected to double as a fingerprint reader that could power a range of security features.
If Apple follows past practice, the phones would be released in late September.
Previous iPhones have cost $199 at launch when coupled with a two-year service contract, but the company is reportedly training employees about a trade-in program that would allow users of older iPhones to exchange those devices for discounted newer ones.
Customers who prefer to trade-in for potentially higher prices can lock in current prices by signing up now on resell website Gazelle.
