Most of my concerns and changes that I would wish to see in iOS 7. Fraser has pretty much nailed it in his post. As much as these are his concerns these are concerns of the entire iOS user community as well. I would like to add that Apple should give a set of gestures like swipe left, right, up, on any screen (app or home) to do a set of user customizable actions like switching back to a previously open app, open contacts/any user preferred app instantly, change(turn wifi or 3g on/off) settings instantly etc. This would help improve the usability on the iPhone. Getting to turn the data on/off is so deeply buried, its down right annoying now and so is switching to the previous open app with double tap to get the multitasking bar and then switching.
