When I do a *3001#12345#*/versions/firware version 04.03.13_G

What does this mean and how do I fix it?

My phone is in a current stat that I have the iphone icon screen with slider ( slide for emergancy ) and the dialer screen. No matter what I do *#307#/delete/o/anwser/hold/decline instead of allow me to use a contact area, it just flips back to the icon screen.

I am very new to this and only have a very basic knowledge of this whole process, so be paient with me please. Thank for all your help.
