I am making an app for iPhone 4 only and my designer files are having resolution of 640*920 .Now I have confused that what is the frame size I have to take when I am making an app.i.e 320*460 or 640*920

Use 320*460. The device will automatically scale the image to fit the pixels.
It might be a good idea to provide a graphic for 320px*460px and lets call that foo.png and then include a grapic for 640px*920px and call that [email protected]. That way if the device is an iPhone 4 or 4s it will automatically use the higher resolution graphic.
