The rumor mill is churning again, and it's saying that not just one, but two new iPhone models may see daylight in 2013. The two iPhones are rumored to be the iPhone 5S and a new 4.94-inch iPhone 6 (or iPhone +.)

This information comes courtesy of laoyaoba.com and a source claiming to have seen the iPhone 5S and iPhone 6 at Apple suppliers. The source also claims the iPhone 5S resembles the iPhone 5, and that the iPhone 6 is the lightest and thinnest iPhone to date.

The report states that Apple is planning to bring the iPhone 5S to market this year, no surprise there. The larger iPhone +, however, is supposedly to be released as a backup against the rising popularity of larger Android phones.
