Saying "the logo" is misleading. Yes, you can use "the logo" all you want, and anywhere you want. But who created the specific logo that you are using and are they enforcing some sort of copyrights on that specific item?
It may be hard, but try to find out who created the item you want to use and make sure that it's okay with the creator that you use it. I assume most of the major logos are under a
http://us.creativecommons.org/ license, or are public domain.
