What we think we know
This early in 2014, we don't know much about what Apple has up its sleeves for the next iPhone. That said, some trends are already popping up in the rumors. Analysts and sources claim that Apple will give us two phones this year, just like it did in September 2013 with the 5S and 5C.
There will be a large iPhone model, likely with a 5-inch or larger screen, and also a smaller, possibly lower-end, device closer in size to the iPhone 5S.
