Lock screen wallpaper not setting on my 2nd gen iPod Touch
I have a 2nd generation iPod Touch with iOS 4.2.1, and recently it hasn't been letting me change the wallpaper for the lock screen. I reset the settings, and it went back to the default black screen, but it still won't let me set a picture for the lock screen. It does correctly display album artwork when I'm playing a song.
I'm not sure if it's just a glitch, or if Apple is messing with older devices to get users to upgrade. I have not tried resetting the whole device, but I will if it comes down to it.
Any ideas? All answers are appreciated.
iPod touch, iOS 4.2
