I have a short list of things that would be nice ( in order of importance to me)
1)BETTER BATTERY LIFE
2)New app and UI management, it's just too damn cluttered now
3)More storage ( ex 64GB as opposed to a max of 32)
4)New notification system
5)Produce a proper resolution video instead of the current iphone screen one
6)Camera and video camera zoom
7)21 MB/S where supported?
8)Camera flash
9)New hardware look. Current one is dated.
10) Oleophobic all over
11) Wireless sync like in the Zunes
12) Custom themes and tones without jailbreak
13) For the love of god a understandable app approval process.
