I've just discovered a cool new service for your cell phone.
Instead of calling 411 to get someone's phone number -- incurring a fee of anywhere from 75ยข to $2.00 -- call 1-800-FREE-411. The service won't cost you a penny besides your cellular airtime, but you'll have to sit through a 10-15 second commercial message which is not overly annoying. It's completely automated, and every time I've tried it, the voice recognition software has worked perfectly for both residential and business listings. The service works from your landline phone, too.
I have no financial interest in this whatsoever, just passing it along. You're welcome.
