Have you ever gotten calls
callers (people who dial *67 to block their number on other people's caller
ID) and wanted to call
them back? Well, what you probably didn't know is that you actually can! All you have to do is set the message as new and press 2 while listening to the message to call
them back. Enjoy this trick while you can before you're forced to upgrade to Google Voice!! WARNING!! This trick DOES NOT work with Gogle Voice so don't upgrade unless you don't care about doing this!! If you are already upgraded to Google Voice then you sadly can't do this trick.
