Blackberry is a device which can connect to internet in many many ways. Each of them are specified as a service book. Different types of transports that are possible are WAP, Blackberry Enterprise Service, Blackberry Internet Service, (old) Blackberry Unite, Wi-Fi etc. When you create a network connection, you will need to specify what type of connection you are interested in.
