An Ars Technica commenter:
In implementing homescreen wallpapers, Apple realised that (as is clear from many Jailbreak themes) custom backgrounds often look rubbish and/or reduce usability. To counteract this they’ve added drop shadows to all the icons and text which make it much more readable / attractive. Unfortunately this runs like crap on a 3G (and you can test this on a jailbroken device, google "enable homescreen wallpapers 3g").
Probably true: the icons and labels inside a folder don’t seem to have drop shadows on my 3G, but do on all the 3GS screenshots.
