Just grab the clownfish wallpaper on your Mac and put a copy into iPhoto. Connect the iPhone and the picture will transfer. On your iPhone, go to photos, open up the clownfish wallpaper, and set it as the iPhone's wallpaper. Zoom in as desired. Boom, original clownfish wallpaper!
nevermind i completely forgot you could set any pic as your wallpaper i was expecting it to be more complex all you have to do is sync your photos with your phone
but i just googled the pic and put it on my phone but the one i have is low resolution and doesnt look as good as it should? Anyone have a good photo that is really clear like all the preset wallpapers?
