doubts on xbee shield v1.1 created by itead studio

Hi friends I have a problem regarding communication between Xbee module and arduino uno can anyone help me out. in shield v1.1 there is no switch between micro and usb mode i am using arduino uno,xbee shield v1.1 from itead studio and xbee2 module

What are you trying to accomplish? You need to figure out exactly what you need before you can setup the tx and rx xbee modules. You need to use a program called X-CTU for the xbee, and you need to put your arduino in reset mode or remove the arduino processor to program the xbee. For instance, if you using it to pass a digital signal, you would use the following setup sheet: http://www.digi.com/support/kbase/kbaseresultdetl?id=2180

Can an arduino mega be used to configure the xbee & if YES how do we bypass the the processor .......how can this be done

"Bypass the processor" is a concept you will need to explain because if you intend on using any Arduino, the best you can do is to echo the Xbee receive to an Arduino pin... However, the Arduino is still running code even then.
