Thanks Pawel  :-)

Understood.  Further investigation showed the RRULE with COUNT= was the
problem.  Not surprising because the phone has no equivalent option; it only
supports end dates, not counts.  Similarly
RRULE:FREQ=DAILY;BYDAY=MO,WE,FR,SU is not supported by the phone (no
day-of-week selection for daily recurrences). 

What to do?  I am contemplating writing a script (awk) to post-process the
Orage export file to change VEVENT types not supported by gnokii and the
phone into VEVENTs that are supported.  For example the VEVENTs with RRULE
lines with COUNT= could be transformed into "until <end date>" type VEVENTs
or a series of individual VEVENTs.  It would be necessary to use a period
such as one month before today to two months after today.

Would this be useful as a prototype algorithm for gnokii or as a workaround
until this functionality is developed in gnokii?    

Best
