Vietnamese website Tinhte, which has a solid track record of getting its hands on pre-release Apple products and accurate mock ups,today posted what it claims are mock ups of two next-generation iPhones. One is the full-fledged “iPhone 5S” upgrade, while the other claims to show the much rumored low-cost “iPhone 5C” that we’ve been hearing a lot about recently. It’s worth noting that Tinhte says the source of the images, Vietnamese accessory supplier¬†PhukienGiare,¬†also supplied the publication with accurate pre-release mock ups of the iPad mini leading up to its launch.

For the iPhone 5S, the design of the mock up appears to be largely the same as the current iPhone 5. Most rumors seem to agree with that much, and the site notes its report from earlier this year that claimed the device will pack in a new 12-megapixel camera. The mock up also shows the dual LED flash that is rumored to make an appearance on the device.

The second mock up shows what the site is referring to the “iPhone 5C“, and shows the all-plastic design that we’ve seen several times in other alleged leaks. The site notes that the Lightning connector looks slightly smaller on the mock up, but it’s unsure if this is just on the mock up or if Apple is experimenting with tweaked connector designs. (The iPhone in the images with the leather skin is an iPhone 5 for comparison).

Earlier this week photographs leaked showing the iPad mini-like design for the next-generation 9.7-inch iPad that we posted of photos of back in January.
