If you get a call on your cell phone from an unknown number and it only rings once . . . don't call back.  Apparently, scammers in the Caribbean have a computer that calls thousands of random cell phone numbers, then disconnects after one ring.  And the phone number it's coming from LOOKS local... BUT! You'll get charged $19.95 to make the connection, then $9-per-minute.  Assuming you hang up in less than a minute, that's $28.95 extra on your next cell phone bill.
