Just got this email forwarded to me, not sure how reliable it is, but here ya go anyway:
Subject: DO NOT CALL - Cell phone registry
Importance: High
JUST A REMINDER....3 days from today, all cell phone numbers are being released to telemarketing companies and you will start to receive sale calls. YOU WILL BE CHARGED FOR THESE CALLS.... To prevent this, call the following number from your cell phone: 888-382-1222. It is the National DO NOT CALL list. It will only take a minute of your time. It blocks your number for five (5) years.
HELP OTHERS BY PASSING THIS ON TO ALL YOUR FRIENDS OR GO TO:
