PNGs over JPGs. I read about it in a iPhone development book. The iPhone OS optimizes PNGs and those are preferred, although JPGs would work just fine.

Once loaded into memory any image becomes a simple bitmap. So in terms of the memory taken up its the same for most or all image formats. PNG may decode faster than JPEG.

I use only PNG's they seem faster to load from my experience...

For what it's worth PNG is also a lossless format (theoretically no quality loss when compressed).
