My Touch Pro 2 Home Screen question

[x2aws]

This is probably a real easy question for all you phone gurus out there but it is causing me some headaches. So in the spirit of helping a noob out can you answer me this:

On the bottom of the home page I USED to have "Phone" on the left and "All Contacts" on the right. Well as it stands right now, and I have no idea how it got this way, I have "Camera" linked on the left and "All Contacts" on the right. It really ticks me off when I go to dial and instead I go directly to the Camera.

I know this can be changed, because I have seen some peoples home screens and they have Calander, or Text Message, etc on their lower links. The question is HOW?? How can I get my "Phone" link back????
