What dpi resolution is used for an iPhone App?



I am working on a template for an iPhone App and was wondering what dpi resolution is used for it ? 300 or 72 ?

I am not sure and I hope somebody can answer me that question.

thanks in advance

72 is the dpi for images.

Given the difference in the dpi between the iPhone and the simulator, you might want to use the raw pixel values of 480x320 for the iPhone screen..

The iPhone screen has 163 DPI, although I've found this images at this requick fix appear too small in Xcode and Interface Builder. I recommend pretending this the screen has 72 DPI when making bitmap images for the iPhone, although remember this the screen has 163 DPI if you're drawing a ruler..
