Champagne gold iPhone 5S images leak.

Japan's ASCII iPhone photo leak

The Apple rumor mill has been thrown into overdrive, as reports suggested the release of two new iPhone models this September, aimed at the premium and low-end markets.

Reportedly due to be revealed on Sept. 10, the two new mobile devices are touted to be a way for the tech giant to "regain momentum" and potentially snag marketshare from rival firm Samsung. 

Published on Japanese website ACSII, the latest leak in relation to these reports shows new iPhones in a selection of colors, including the rumored champagne gold. Although unconfirmed, these images do seem more plausible than many floating around online.
