Apple to Unveil Next Generation iPhone on September 10
The iPhone 5C, which is aimed at emerging markets, shares quite a few similarities with the iPhone 5. Prototype photos and leaked parts have depicted a similar shape and size, though the iPhone 5C has rounded edges, a slightly thicker form factor, and a polycarbonate shell that is offered in a range of colors.
The most recent rumors have suggested a price tag of $490 for the device, which is in line with iPhone 4 pricing when carrier subsidies are taken into account.
Apple's upcoming iPhone 5S is expected to feature a design that is similar to the iPhone 5, but with a number of improvements. It is rumored to include a fingerprint sensor, an upgraded 12-megapixel camera with a dual-LED flash, and iOS 7. It is likely that iOS 7 will become publicly available after the announcement or when the phone debuts.
Though OS X Mavericks is also scheduled to be released in the fall, AllThingsD does not expect the software to be debuted at the September 10 iPhone event.
Update: iMore's Rene Ritchie reports that his sources are also indicating a September 10 media event.
