just got my evo today and i was playing with it for hour. i didnt do anything other than install apps from the market and install swype. I changed my wallpaper to the water one and i restarted my phone and it was back to the original carbon fiber like background. i thought it was weird but i ignored it. a couple hours later i wanted to try restarting again so i did and it comes back on with no background at all, so i went back to the options and tried to change it back to the water background and nothing happens. I still just have a blank evo background. the only time i can see my background now is if i go to my lockscreen.
