Blackberry's also allow for the creation of custom applications.  If
you're talking about the units from Motorola that I think you're
talking about (the new Accompli line), those have a
proprietary development environment which prohibits the development of
apps which aren't provisioned by a wireless provider.

Or is there a new unit coming out?

Be aware that when you use PIN-to-PIN messaging, the key used for
symmetric encryption is not secret.  That's why RIM talks about those
messages being "encoded" rather than "encrypted".  Decoding them is
trivial: the key is known to every RIM Blackberry device.

Email using their email backbone is encrypted using Triple-DES and a
key sharing scheme which has passed muster at a variety of very fussy
organizations.  

But, as I asked in my previous message, we still don't know the threat
profile.  RIM Blackberry units are probably susceptible to
electromagnetic eavesdropping (different than sniffing the DataTAC or
Mobitex packets).  I haven't really explored the internals, but I
doubt they'd hold up to someone who has actually acquired the physical
device and wants the data inside.

What is the threat against which you define "secure"?

Probably the question asked most often is: Do one-celled animals have
orgasms?  The answer is yes, they have orgasms almost constantly, which
is why they don't mind living in pools of warm slime.
