I currently have a custom unlock sound using Winterboard's UISound folder. From what I understand, people can use HTML to have rotating backgrounds, but can this also be used to rotate other aspects? Basically, what I would like to have is have a rotating unlock sound based on the day of the week. This may or may not be possible, but I was hoping that someone would have an idea as to how to go about this if it is possible. If it's not possible, that's alright. I suppose I can just SSH every once in a while and change the unlock sound. It just would be nice if I can have it done automatically.
