Production phones don't ship with root access, developer phones do. If you have a production phone (likely: you'd know if you bought a dev phone), you have to "root" them first. As @Joe_Casadonte points out, there are some great instructions here and elsewhere (Notably the CyanogenMod Wiki and Android Rom's google group) to get you started rooting your phone. (And if you get stuck ... come back here with your questions!).

Once you've rooted your phone, you can gain root privileges in the adb shell or the terminal emulator with the su command.

Note: it sounds from some of your responses like you haven't yet rooted your phone. So you'll need to start there.

Type su and your terminal prompt should change from $ to #. This is assuming that your device is already rooted.
