Just received this e-mail and wanted to post it.  I registered on the do not call list but can't remember how long ago that was.  So here is the info:

REMEMBER: Cell Phone Numbers Go Public this month.

REMINDER.... all cell phone numbers are being released to telemarketing companies and you will start to receive sales 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. You must call from the cell phone number you want to have blocked. You cannot call from a different phone number.
