Apple Space Vortex- iPhone/iTouch wallpaper Here's a little wallpaper I made as a request on my graphics shop. It was made completely from scratch except for the Apple logo. 320x480 - 97kb It should work fine on your iPhone or iTouch because its 97kb, which is just below the 100kb limit. Feel free to use it but please give my some CnC too. Download: Space Vortex: iPhone+iTouch wallpaper- deviantART
touch of blue could be good 97kb is quite large for it... RST's sig is only 75kb and his has quite alot of colour, so i think you should look into compressing it or making it a smaller file(flattening image etc.)
I tried that just now, and it turned out to 106kb. I think it looked a little worse too. Ah well, it was worth a shot.
I don't actually own an iPhone or iTouch, but I researched the topic and I learned that all you have to do is download the image, put it in a folder, and then go into iTunes and sync that folder. Any image in the folder should be available for use as a wallpaper.
