Do you have any indication from Sprint how long they will be keeping their 4G (WiMAX) network, now that they have shifted towards LTE tech in their long-term plans? Specifically, how long will my Ting 4G (WiMAX) phone continue to have any sort of 4G service? Will Sprint still have access through Clearwire's WiMAX network (as it does now) in 2013? 2014? 2015? Or is investment in a current 4G Sprint or Ting phone to be considered a short-term thing, to be made obsolete next year or the year after?
I read Sprint says they will continue selling WiMAX devices through 2012. Since they are sold on 2 year contracts, does that imply Sprint may shut down its WiMAX service at the end of 2014, figuring on selling new LTE phones - and contracts - to its 4G customers then?
