WLAN_STATE_CONNECTED; } Data connections using BIS-B and MDS are handled differently. Both of these connections route data traffic through the BlackBerry infrastructure and support seamless routing across networks. Because of this ability, the network connection libraries that contain the special programming logic needed to switch networks automatically include the ability to switch from a carrier network to a WiFi connection. What this means for the developer is that, if you’re using BIS-B or MDS connections, your data communication will automatically switch to WiFi when a Wi-Fi connection is available; there is nothing your application needs to do to detect or act upon the availability or loss or the Wi-Fi connection.
