I was guessing that the reboot-every-few-months recipe was trying to dance 
around the week number roll over issue.

Has anybody figured out where/when it writes whatever it needs so that it 
comes up right on power up?

On the initial application (cell towers?), was there any expectation of 
lifetime?  In particular were they expected to keep going over WNRO and/or was 
there a difference between run over WNRO and spares sitting on the shelf 
coming up after WNRO?
