A basic idea of mine is to develop an iphone applet that is able change its wallpaper dynamically. The information to be displayed in the wallpaper will be disclosed lateron. I was thinking to let the iphone applet be able to change the savescreen-wallpaper with my latest agenda appointments, scheduled to refresh every 5-15 mins.

However I was told unable to get it implemented on iPhone platform, so I decide to try the Android, but I don't know anything about Android market, can you please provide assist? Thanks very much.

I am willing to know your suggestions.
