Rumors suggest that Apple could be working on an 4.8-inch smartphone that could launch as early as this fall. Code-named the iPhone “Math,” the handset is said to come with a 12-megapixel camera unit.

Now the folks at Russian-site AppleDigger are out with what appears to be the first mockups of Math, plus a video. As you can see, the site conceptualizes an iPhone that would be available in multiple colors, as per previous rumors, with six rows of icons.

Take a look:

As Aldrin Calimlim first reported, the Math is only one of three possible iPhones that Apple is said to be working on. The others include a more traditional handset, the iPhone 5S, and a less expensive model for emerging markets. Production for all models is said to begin in late April, with Foxconn handling 90 percent of the manufacturing orders. Largan, Fujikura, Flexium, Coxon, and Foxlink are also mentioned as prospective suppliers.

It should be noted that sites such as Digitimes have recently backed off previous claims of an iPhone Math, at least for 2013. Instead, what we are seeing here could be a concept of the iPhone model set to launch in 2014. Apple has traditionally released a significantly different iPhone model followed the next year by a more modest update. Think, for example, the iPhone 4 followed by the iPhone 4S.

Regardless, we thought that it was important to show our readers AppleDigger’s concept. Enjoy!
