Here are over 100 backgrounds from the many Harry Potter movies that will nicely light up your iPhone 4, at 640 x 960 pixels in size.
Please click on the background you want to view, then download it after it appears at full size. I don’t know how to download it cause I’ve never had an iPhone. 
Please click here for Harry Potter wallpapers of all sizes, iPhone and Blackberry backgrounds, printable cards and Facebook tagging memes from HP 1 to HP 7-2.
