Is this the last time we will see the iPhone get a increase in size of the screen? Samsung and various other companies continue to increase their screen size of their phones and they reached the limit to what fits in a palm. Will Apple always keep this 4" screen or is there a possibility they will once again increase it since they still have room to? Anything over 4.7" is too big to be comfortable in the hands of the general user which Apple won't do. 4.5" is the ideal size but will we see this from Apple?
