An article in the Wall Street Journal's Personal Technology column describes ChaCha's free cellphone service that allows you to ask any question.  Call 1-800-2ChaCha or send a question via text message to 242242.  While the service is fee, regular text messaging/call costs from your carrier may apply. 

The questions are answered by a team of ChaCha guides that are paid a set rate per transaction/answer.  If you're interested in trying the service out and want to learn how it works, here is a link to ChaCha's FAQ.
