I have one application which is on iTunes now we build this app for iphone SDk 3.0 and above but when we running this app on iPhone SDK 4.0 then the resolution of images will decreases so it look very bad.
So can any one give me the solution for this how to overcome this problem.
Thanks.

well … the resolution of the images do NOT decrease … Instead the resolution of the display is changed, and the image is displayed in the same size on a higher resolution display. That’s why it looks so bad.
You need to save your images in 2 formats. Normal and high resolution.
Here you have a good article on what and how to do it: http://useyourloaf.com/blog/2010/6/29/updating-for-the-iphone-4-retinal-display.html
