Nokia Bots, the Beta application which was introduced a while back has now been updated to support Symbian^3 devices.
Nokia Bots is a collection of add-ons that autonomously learn your personal preferences, and improve user experience with new, customized features and tricks. These add-ons, or Bots, observe how the phone is being used and automatically configure and activate themselves, if customization seems relevant.
You can find out more about Nokia Bots here over at Nokia Beta Labs where you will also find the download, and instructions on how to get started using Nokia Bots. You will need to be signed into your Nokia Account to access the download page.
