Nexus One Wallpaper Toolkit
I’ve looked around the web for the correct size of the wallpaper and a way to control what content is visible on a specific home screen. In fact the wallpaper is not scrolled 480 pixels when you change homescreen. After various experiments I’ve come up with a photoshop file where the guides are ready for you to design your own wallpaper for your nexus one. It’s for for you to download. Enjoy.
