Don't want a larger screen. Maybe 1/4 of an inch wider but 4" is fine height wise. I hope we continue to see improvement to the camera with 10MP probably coming but more importantly image stabilisation, face recognition and other functionality will be welcome. Particularly low light capability. Maybe some form of virtual keyboard technology? Further improvements to speaker and microphone capability. Lets hope Apple don't continue to boycott NFC. And battery life still needs to be improved (possibly with wireless charging may mitigate this issue). Personally, I don't care about tear drop changes to form factor. Anything else I have left out.
