Can the Arduino read the digital I/O pin status of an XBee using the relay shield v2.1, considering XBee's 3.3V logic level?

With your relay shield v2.1 is it possible for the Arduino to read the status of some of the digital I/O pins of an XBee? Because the XBee is 3.3 volt there would need to be a logic level converter on the board, I believe.
