I loaded a wallpaper into the DCIM folder on the internal memory and after disconnecting from the computer, I changed the home screen wallpaper to this picture. (the one of the predator and alien playing chess) Now all 7 home screens are completely blank. No widgets or icons. Somehow everything on the home screens has been wiped. I removed the picture from the internal memory folder...rebooted.... tried removing the battery....nothing has helped. Any ideas?
