ImageView DPI

[Vortec4800]

For all of the graphic elements in my app I've been using PNG files @ 72 DPI - but I've just noticed that Apple's spec on the iPhone display shows that it is 480 x 320 @ 163 PPI. Should I be creating these images at 163 DPI to get the best possible image on the display?

I do not believe that PNG stores DPI data, nor does UIImageView use it. As long as you have the correct pixel dimensions you should be fine.

Images created on my pc using fireworks at 72dpi, in imageview are reported as 71.5, don't ask me why. They were accepted as part of the submission process
