From the official doc of Blackberry, between BIS and and the blackberry device are not encrypted (other than wireless network security). I also hear or see possiblities of this is encrypted in the GME protocol. Is this operator dependent? Thats some operators ask encryption between BIS and the BB device and some dont. Irrespective encryption or not, can I tell at least what service (e.g. email, BBM, web etc) a particular PIN or MSISDN that is accessing, although the content is encrypted?

We know BES and BB device communication is encrypted. Since it is mediated by RIM NOC and the concept of service book and SPR ID, does this mean that from the Gp interface at wireless network, I can tell at least what service (e.g. email, BBM, web etc) a particular PIN or MSISDN that is accessing, although the content is encrypted?

Thx for the help
