A pretty legitimate looking leak of the new iPhone has shown up this morning on Chinese site cnBeta. This is the 4.7 inch version which looks significantly larger than the iPhone 5s. I was hoping it wouldn't be quite this large as I like my iPhone sleek and small.
There will also, allegedly, be another version that is 5.5 inches. So basically an iPad Mini with a phone chip in it.
Here is the new phone sitting next to the older iPhone 5s.
