I just got new blackberry, How do I set up which applications is displayed on the Home screen?

I got a new Blackberry Curve the other day. The home screen display shows several applications including Messages, Calender, Call Log and Applications.

Is there a way for me to change the applications that are displayed?

Click the main blackberry button, (the one beside the green phone button). Here you should see a full list of all the blackberry applications. The first row is what appears on the main screen. Move the application you want up to the front row.
