I'm pretty sure it's possible without jailbreaking because i've seen people with it and they didn't jailbreak it, so can anybody tell me how to change the background on an iPhone 3gs BEHIND THE APPS, not the lockscreen?
Again, I have a ****3GS****, not 4 or 4s.
go to settings, then wallpaper, choose your wallpaper from your photos, put it as you want, choose home screen, then wala you'll find it behind the apps
if that doesn't work don't pick me as best answer.
