UV mapping help?

I am currently learning how to work blender in my 3d design class at my school. We are currently using version 2.45 while my computer is using 2.49b. My question is, how do I go into UV map face selector? At the school we just went from object mode to UV face select mode but I can’t find that option. Do any of you know how I can get there or how I can apply UV map images?

Just go into normal Edit mode, that now includes the face select mode.
