Presumably, though, at some point, then either the obsolete CDMA networks are going to be taken out of service, to free up the bandwidth for other purposes, just as, in the UK at least, the old analogue cellphone networks were taken out of service some years ago. or, when the number of "old" Kindles falls below some critical level, Amazon will cancel their contract with Sprint (just as, for example, Palm pulled the wireless service that was used by the Palm VII). At that point, then obviously the wireless delivery on "old" Kindles will stop working.
But I suspect that any such actions will be several years down the road.
