You have to unlock it first. The whole idea of this type of lock or passcode is that nobody who doesn't know the secret code can access the phone.
Click settings and choose phone settings or go on your photos and go onto options, use as, then click wallpaper.
Go onto settings Then screen settings click on wallpaper and change it there on go to your images go on the photo you want Click options use as Wallpaper :) Hope this helps :D
Nope. You can only change background and screen wallpaper.

On the Home screen, press and hold the Recent Apps key and tap the Wallpapers icon at the bottom of the screen Scroll through and tap thumbnails to view the available types of wallpaper. To apply an image or live wallpaper shown in the scrolling list, select its thumbnail and tap Set Wallpaper.
You can't. I know, it stinks

Update to iOS 4.0.1, then go to wallpaper and change lock screen wallpaper and home screen wallpaper. It wont work for iPod touch 3g and under and iPhone 3g and under because apparently it will slow it down all the new features.
Enter your 4-digit passcode. If it is not your iPod Touch, do not attempt to hack it, since hacking is illegal in most places. If it is your iPod, you have to restore it through iTunes if you forgot the passcode.
Set a wallpaper by going to settings>wallpaper Choose a pre-installed wallpaper or choose one from your photo library. On 4th gen, you can also set a separate wallpaper for the home screen. When you jailbreak your iPod touch, you can download winterboard themes to also change icons, battery icons, the dock, the lock screen, and much more.
