Okay.  Blackberry question.  I really want to know the answer to this,
because I've heard a LOT of misinformation.  I have done extensive
research, and still haven't been able satisfactorily to find an
answer.  Thus, I am going to set a HIGH price for my question, but I
will **NOT** give consent that I am satisfied unless the answer
actually answers my SPECIFIC questions.

Here is the Q:

If I have two blackberry units, one that is for work and one that is
personal.  And if I have my work calendar information (appointments,
etc) on the one, and my personal calendar information on the other,
a.) can I, and if so, HOW can I
1.) sync up BOTH separate calendars on to ONE instance of Outlook,
such that I have a MERGED view of BOTH my personal schedule and my
work schedule?
2.) If such syncing is possible, what happens when a work appointment
and a personal appointment overlap (partly or completely)?  Do they
just get double-booked, and I just have to resolve that?  Do they get
flagged?

3.) Can I do this on my personal computer, or does the fact that one
of the blackberries is a work blackberry, MUST I do it on my work
computer (ie, bring my personal appointments on to my work outlook as
opposed to bringing my work appointments over on to my personal (home
computer) outlook?

4.) As an alternative:  I know one can sync Outlook with Yahoo!  If I
cannot merge my personal and work calendars into one instance of
Outlook, could I take my work calendar and upload it to Yahoo, and
then take my personal calendar and upload it to yahoo, such that the
two calendars are merged in to one?  Will Yahoo handle that?  Or will
it do funky things like, for example, the following:

1.) upload personal blackberry calendar from outlook to yahoo.
2.) upload work blackberry calendar from outlook to yahoo.
3.) Since dinner with friends on a thursday night (a personal event
obvi) does NOT appear on my work calendar, does yahoo take the absence
of the event as a signal that it should be DELETED?  IE, does anything
that is already on Yahoo, but not in my work calendar, get deleted
when I upload my work calendar from Blackberry to Yahoo?

I very much would like help in these questions regarding syncing
multiple blackberries.  I in particular interested in the calendar
functions, but if you have thoughts on the syncing of contacts as
well, go for it.
