i've been trying to set a wallpaper for my wm6.1 using the function at settings for Today screen, but whatever image i choose turns grey....is there any specific settings or resolution i need to set the images?

no idea?

You can use your Pictures & Videos to view the picture you wanna set as wallpaper (Set as Today background) and then set the Transparency Level to 0%...

really like to help out ... but it is not so quite clear on what you like...

if you like your own theme... you can always use themegence

here is teh link

you can customize your own theme or what we call .tsk put it on your storage card and you can have a pictures and everything that you wish to modify

but you must know first if your pocketpc is a vga or qvga to fully utilize your pocketpc
