The screen size is not so much the issue as the form factor. I am all for fitting a bigger screen on the same size phone if they can.
Yea I agree. By the looks of this though, the 4,7" phone will be bigger than the 4".
I have an eight year old daughter. The iPhone 5 is allready big for her tiny pockets. Apple needs to atleast have one phone model to accomodate kids imo.
