I have had my D3 for less than a week. ! love it! So much faster than my D1. The last couple of days, when i plug it in to charge it at night, a weird thing has been happening. My wallpaper is reverting back to the diagonal gray lines that the phone had on it when I first got it. I am using the "Backgrounds" app for my wallpaper. Has anyone else had this issue? It has only happened the last couple of days. I have to go back in and change the wallpaper every day now.
