Only fourth generation only. Settings you go to app and click wallpaper?
There was an update for the ipod touch about 7 months ago and it allowed you to change the background on your ipod and you can also change the lock screen
you cant
Add a background image to the iPod Touch via the Photos tab while the iPod is connected to iTunes. You can then select the image in the iPod's settings and set as wallpaper. (See links below)
settings/wallpapers
you go to menu and stuff
You need to jailbreak your iPod Touch to change the background behind the apps on your iPod Touch. You can only jailbreak your ipod with windows.. not mac .then download Cydia and Winterboard , you need BOTH.It's kinda hard to figure it out at first but then you get used to it ...
To change the background on an iPod touch, navigate to pictures and click on the picture you would like as your background. There will be an arrow coming from the box, click on that and select make background. You can also download various themes which include backgrounds as well.
It restores all the defaults that come with the ipod. i.e.: the security settings , background... etc.
Backgrounds and multitasking are only available on the iPhone 3Gs, iPhone 4, iPod Touch 3rd generation, and iPod Touch 4th generation.
It depends on what ipod gen. you have. For ipod touch generation 1, 2, and 3, you can't put a background unless you jailbreak your device and get the right app from Cydia. For ipod touch generation 4, select the picture you want and set for your homescreen or wallpaper. As far as I know you don't need to jailbreak Itouch 4 to set a background. :P
You have to settings and choose a backround u want.
You have to go to settings, click on background, they will give you a variety of backgrounds or you could go to camera roll
