the new IPHONE will have a redesigned screen

apparently their will be a delay in the shipment of iPHONE 5 due to Touch Panel Issues .

if it is a 4S then i doubt they would have trouble producing the same screen they have been producing for more than year , wont you think ?

this must mean the new iphone will have different dimensions for the screen , possible meaning a new design.
