okay, so i want to create a theme for the iphone 4. i'm not sure what size the icons should be though. What i thought at first was that all the icons could just be square and ios would just add the roundness and shadow automatically. now what i'm seeing is that you need to make the built in icons (like mail, phone, ipod etc.) a bit bigger than 114 px, so that you have room for the shadow, and you need to add you own roundness to the corners, but on third party apps you can make them square and ios will apply them to the app/game. is this true? do you need to make the round corners and shadow on the built in apps and leave the 114 px square for third party apps?
