Thanks, your last remark is apparently what has occurred twice.

The solution should be to back up the data to the computer using a cable
and the Nokia software, then reinstall from the backup; however, that
software for some strange reason will not install onto my computer.  No
one around here knows why, and Nokia USA doesn't know anything because
they don't sell the 6260. (Tried install unsuccessfully several times
over a year.)

Perhaps I need to attempt install on someone else's computer the next
time I'm traveling -- and perhaps even the try the same here at home.

After having lost all mailing addresses, etc., for two months, at this
stage am ready to give up on Nokia and the next phone will be a
different brand.
