Of course, with the six it will be like a 5 inch screen. Then the seventh with a 6 inch screen and so on and so forth lol. I honestly don't see what more they can give you in a phone then apple already has.
I think they should could the new iPhone the iPhone S, or the iPhone X. That would sound really cool. I think it would be ridiculous of they kept going 1,2,3,3GS,4,4S,5,5S,6,6S,etc. They should kind of refresh the naming.
