Hmmm... It might just want an odd sized wallpaper - I dunno. Can you maybe check the size of one of the wallpapers it came with? Gallery or Photos > Wallpaper or All Pictures > find a stock wallpaper and select it > Menu > More > Details > Resolution. Also, someone here a while back wanted a size that I'd never heard of being right for any Android, but he said it worked for him. So maybe give this size a try... Picasa Web Albums - eyebeam668 - Android wallp... I'm pretty close to stumped here - sorry.
