iPhone 5S, 5-inch iPhone 6

The much-rumored iPhone 5S and a 5-inch iPhone 6 have shown up at an Apple supplier in China, according to a post on a Chinese microblogging site.
The models could be released this year, according to a post by a Sina Tech user called Old Yao. He reports that a friend of his at a supplier has seen the models and says that the iPhone 5S resembles the iPhone 5, while the iPhone 6 is wider, longer, and thinner.
CNET has contacted Apple for comment and will update this report when we learn more. As Apple gets closer to an anticipated launch of a new smartphone, the speculation and rumor mill go into overdrive, so while Old Yao's comments are food for thought, they should also be consumed with perhaps more than a grain of salt.
Earlier analyst speculation held that Apple would release an iPhone 5S and a revamped version of the iPhone 5 in June or July. KGI Securities analyst Ming-Chi Kuo predicted last month that the new S model would resemble the current model with a few improvements, including an A7 chip for faster performance and a fingerprint sensor.
A larger screen size for an iPhone 6 might attract consumers smitten with Samsung's 4.8-inch Galaxy S3 and 5.5-inch Galaxy Note 2.
