Custom wallpapers are blurry/fuzzy?

[iBoost]

Hi peeps, I'm a graphic designer and I have several custom iPhone wallpapers that I'm working with and they always look blurry on the iPhone. I know dimensions are 320 x 480 and I have tried resolution both at 72ppi and 180ppi. What can I possibly be doing wrong? Exporting as .jpg and .png both look blurry. Normal wallpapers look fine.

Thanks

Are you emailing the photos to your phone? If you are and you're not already on 2.2.1, you should change to that I think, as this was a pre-2.2.1 issue.

I'm downloading from my server online, like a regular wallpaper. I can't understand why?

Well the bug does affect images downloaded from the web as well.

2.2.1 is supposed to fix it.

It seems to be to do with certain picture sizes. There's a few threads about it here:

You may solve it by synching the photo from itunes, or maybe by changing its size
