Haven't tried myself but you can put the pictures onto a USB and then onto a computer and email yourself the pics. That's how I would do it. But I don't know if you can go ps3 to iPhone. Since I have a iPhone I would like to know as well.
And you don't need internet access. All you need to do is move the images from your ps3 onto a removable storage device such as a USB flash drive, move that into a folder on your computer, plug your pgone into the computer, open iTunes, go to your iPhone, go to the Pictures tab, and when it asks you which folder you want it to sync photos from, designate the folder you made containing your images, Apply Sync, done.
