Good that they give you some support anyway. Ask them what expected 
endtime they have for the new FW. The reason you are interested in it is 
that you and anyone else want to know before which date you need to make 
a planned decommissioning of the units.

I know one set of 9390 that is being decommissioned as result. They 
where already scheduled for decommissioning eventually, but they where 
not too happy about the early self-decommissioning that they 
experienced. Had they known the end time of FW support was in GPS week 
1524 they would have either received FW upgrade or been decommissioned 
in an orderly manor.

This is how we should handle this in the long run. We need to know these 
things so that we can make meaningful operational decisions on GPS 
receiver equipment, wherever they are. I will have to inform my 
customers as well as others have to. We also need to verify this, partly 
just to verify what is stated but also to discover what is not stated.
