With older versions of iphones, my custom buttons look crisp, but on the iphone 4 my buttons look really pixelated. How can I fix this. I have a a series of buttons that are 75x75px, Do I need to make them 150x150px and add @2x to the end of the buttons name (will Mobione recognize this)? And if so do I need to add a new css file or a line of code to existing css?
I know those are a lot of questions, but I am so confused.
Wayne help!
