I want to know how connection is established between my BB phone and BES? Is connection based on my mobile service provider or some other thing?
Can u tell me ,how is this?
Usually a Blackberry is used in a corporate environment. Using the Blackberry MDS Dataservice a connection looks like this. The datastream is encrypted and compressed.
