Apple ipod

I have the new iPhone 3G S and zoom! HELP!?

S I have an iPhone 3G I know I can bring when I'm in Safari and my photos. My problem is that somehow all my icons are very big blow, as if I zoom in the screen of my home. How I can get to be back on the size that is supposed to be?

Contact Apple or AT & T
