Well finally we have Nexus S 4G on Sprint and it's good for us as it comes with Integrated Google Voice features.The new Nexus S 4G from Sprint Nextel comes with Google Voice built-in to provide users with an easier way to go about dialing numbers and executing a wide range of actions with their phone without even touching it.

I think price is excellent and good to see we have much better one compare to T-Mobile Nexus S as from this source:
