4-inch iPhone display does not bother iOS developers

For the first time since its introduction in 2007, the iPhone will have a physically larger display, or at least that is what all those rumors claim. If that happens to be true, the display's resolution will have to be altered, supposedly to 640 by 1136 pixels. But does that really bother iOS developers? Will they have a hard time redesigning their software in order for it to fit the new display?
Making apps fit on an "iPad mini" would be just as easy of a task, most developers responded. If rumors are to be trusted, Apple is planning to introduce a smaller iPad model with a display measuring about 7.85 inches in diagonal. This rumored iPad model will supposedly have a display with a resolution of 1024 by 768 pixels – just like the iPad 2 and the first-gen iPad.
