Hey,
 
You probably have inserted a different SIM card from the one that your phone originally came with. The message implies that your device is locked to one network (the one it originally operated on) and that you are you should unlock it first in order to proceed. To unlock it to all networks you will have to purchase an unlock code (each device uses a different one). You can purchase this code from www.unlockunit.com
 
See the video here for direction (the video is not too clear though - but you should be able to get the general idea). http://www.youtube.com/watch?v=tMFc3BH40aY
