An update on an existing Iphone game in Cocos2dx

I have an existing Iphone game in the appstore but I want an update for it. Probably entails about 15-25 hours of work. I have a list of the things to be done below as to a summary of what is to be done

-Scores on classic mode have 2 extra zeros on the end of the score on the highscore page. Needs to be corrected.
-When you crash into another trolley on classic need make sure the next item comes along conveyor belt straight away
-Removal of tilt function and remove this on the how to play page also
-Remove the credits page altogether
-Look into a possible bug with ipad and having atominx as the icon
-Look into bug with regards to ipod/iphone - trolley moves very slow and long delay after you crash into a trolley - very common problem from people I have spoken to
-In how to play change "press screen to grab items" to "press corresponding arrow to grab item."
-When the 3rd wrong item is picked up (both classic and arcade) instead of saying game over straight away can you have it so that the splat continues as normal with a "game over" printed over the splat before it goes to the game over/high score page.
-Addition of 1 or 2 more screenshots on app store so to show oncoming crates/ trolleys
-Make sure that everything is retina display (fruit on conveyor belt and baby look as if they may not be?)
-When nearing end of game when screen flashes red moving the trolley left/right is jerky - bug?
-Can the main/arcade/classic/how to play menus instead of having a blue background have the shop floor as the background
-On the description of Turbo Trolley on the appstore - could you change it from simulation to arcade and also add action to the sub category as well as racing which is on there already
