iPhone's Wallpaper with notes and calendar events [AppStore, Free]

Wallpaper Labeler (AppStore link) and gCalWall Lite (AppStore link) let you add appointments and notes to the home screen. With Wallpaper Labeler, you can enter any text you want to your wallpaper, so you can leave yourself (or whoever finds your phone) notes. The other app, gCalWall, pulls down upcoming appointments from your default Google Calendar and splays them all over your home screen. You have to update it manually, which is kind of a drag, but the dev says that iPhone API won't allow for automatic updating. Both apps are free

In the past you could only use Intelliscreen paid app on a jailbreaked iPhone.
