Best Calling Card

With these being the two main iDen providers, I feel for Nextel or Boost to grow is to expand coverage. SL has roaming agreements in place but Nextel/ Boost does not on SL networks. While PPT would be difficult to do because of different numbers, the text, web and voice can. IF both would work together, PPT could cross each others networks. I think IF Nextel acquired SC would be something worth doing in the long run, this would expand coverage starting in the Southeast with spare equipment to go in other areas. Your thoughts?
