Hello and thank you for your question. At this time there are still a number of things that need to take place for the deal to become completed. The deal still needs approval from federal agencies such as the FCC and DoJ. The expected deal closer time is set for mid-2013. Details regarding the use of the Sprint network and logistics for moving over will be communicated at that time.
