Here in northern Delaware, one feature as stated in the phone book is that you can dial some sequence after you've recieved a call to find out who it was that called you. There is something like a $3.00 charge, and it's not available on some phones. Also, it's definitely relatively new. I don't know anything about how it works, though. Andrew.
