to have a song(not the default preloaded tones) as ring tone and homescreen wallpaper

[savio#WP]

id like the new update to have a service provided that would enable you to keep a song as a ring tone instead of only having the option of a preloaded tone...and a service to allow a backdrop(wallpaper/image) for the wp7 homescreen.

You can make custom ringtones with the mango update. You can also make the lockscreen any picture you like now if you wish.

You can have any picture as the lock screen but not on the home page with the tiles.

Or do you mean something else savio?
