Is there a way of setting a different lockscreen image to the one displayed on the homescreens? Home screen images, by their very nature work best when they are simple or abstract because they have a load of stuff going on over the top of them. But in the lock screen it would be really great to see a proper picture, where it doesn't matter what's going on because there's nothing in front of it! It's a small request, but it would be nice to have all the same! Any apps that can do it??
