iPhone 5 to have larger screen?

DigiTimes is suggesting iPhone 5 will gain an extra 0.5 inches to to the screen, giving it a 4 inch screen which is popular with many Android devices such as the Samsung Galaxy S. The home button may disappear from the bottom of the device to be replaced with new gestures as Apple was keen to demonstrate in the beta of iOS 4.3 for the iPad. How this might affect the resolution of the screen, and in particular the compatibility with current apps will remain a question to be answered.
