build a wallpaper for your iPhone, Nexus One or other mobiles !
In order to preserve the image quality, the wallpaper is scaled and resized at the desired dimensions. Anyway, just in case that screen dimensions of your mobile do not fit the scaled wallpaper, you may crop the image and choose whatever zone you like. Select mobile brand, or resolution, press submit, next press build image link, then click prepared image - click here to download !, and save it to your computer.
Next, use Bluetooth, USB data cable, or whatever device you have, to transfer the image from your computer to your mobile phone, and volia !, you’re done. Of course, te bigger screen resolution you have, the better effect you get ... :-) !
