Hi Mike,

As far as I know, the situation with BlackBerry is as follows. If
you're an enterprise customer, you generate your own encryption key
for BBM (I don't know whether it's used for email too), and run your
own server. RIM claimed in August 2010 that it didn't have access to
the encryption keys generated by enterprise customers and couldn't
observe the content of their communication. The statement didn't say
whether RIM could observe metadata.

If you're a non-enterprise customer, your BBM messages are scrambled
with a key that's built into all BlackBerry devices and known to RIM.

RIM has come under pressure from several governments to decrypt BBM
messages, so I think it's safe to assume that the key used for
scrambling non-enterprise BBM messages is widely known by now.

For both enterprise and non-enterprise customers, if you use a
third-party email provider, that provider will have access to content
and metadata regardless of what device you're using.

I don't know whether wireless carriers can observe the metadata of BBM
messages; they could collect the scrambled messages of non-enterprise
customers, for descrambling by anyone who knows the key.

Cheers,
Michael
