I created a brand new background for WM7 and figured I would share it out. This one is interesting because its transparent when unlocking the phone for the first time. You will have to take the file and either download it to your phone from this site, or send it to your self via email. The actual background is in the Zip file. The picture is just to show you what it looks like.
Once done, just open it and “use as wallpaper”.
Know issues with transparency:
1. Does not work with pin lock set
2. With certain apps open (like email for instance), you will see the bottom soft buttons through the wallpaper
