too bad its pentile, so 4S screen > what you have
also this is personal taste but fuck having a mini tablet in my pocket, I like the size of my 4S and if the next iPhone is just slightly taller with a 4" screen that would be nice too, but too much bigger than that would be annoying.
I've used both Jellybean and iOS6 before and then I realized one day; its a fucking phone. Who cares if you can put gay widgets and shit and video wallpapers on your homescreen. Bet your battery will last real long with all that unnecessary stuff. I've seen you hate on the iOS homescreen in other threads, if all your doing is launching apps, then whats wrong with it looking the same, it makes it very easy to quickly open what you need. The iPhone sells well because like Asian Allen said; people call, text, listen to music, take photos and check their social networks, beyond that who cares how much useless shit you can do with a rooted phone, I jailbreak mine to make the UI faster to navigate, not to "do anything I want". Besides overclocking (why...) which you specified, what the fuck do you do?
Again, its a phone, I feel like you take it to seriously
