so on an eight gig 2nd gen ipod touch, can you do wallpapers? i have heard you can and cant. and im not sure how to do it.
nope...takes up a bit to much ram for apple...wait for jailbreak and you'll get alot more...themes that change lot more things(icons, battery)
When I was "jailbroken", I used an app called Winterboard to customize my themes and wallpaper. It's a very nice program, but on 1st and 2nd generation devices, it's a SERIOUS battery drainer.
