[Dovecot] Help! OT: Blackberry IMAP client suggestions/experience needed

[Stewart Dean]

The CFO of our college, a most formidable man, had decided to go Blackberry and 
Something Functional Must Be Done.  We've had some users who we've not supported 
(and things got better for them when we switched from UWIMAP to Dovecot).

BB, of course, has their half-baked sorta-IMAP-compliant client (and we do NOT 
want the BB Enterprise Server) that persistently keeps grabbing the mailbox and 
breaking the mailbox lock, causing no end of grief for the secretaries (plural, 
more than one) would also work with the mailbox.
1) Does anyone have recommendations and experience with a genuine BB IMAP 
client?  Googling shows up LogicMail....
2) I have been avoiding the plunge in multiple-access mailbox and just let the 
early BB adapter users thrash but I suppose it is time to do what I can with DC.
We are running 1.0.12 with mbox format.  Would some kind person <grovel,grovel> 
tell me where I should start reading plus any warnings.  BB DC experience info 
would be a big help.

Our CFO has a legendary temper and I would like to get as much as possible right 
the first time out...........
