Re: Open Tunnel

Do you mean that your account does not allow for direct TCP connections, or that you do not know the APN settings to create a direct TCP connection?  This is required for a direct TCP connection.

 

Or you can make a connection through a BlackBerry Enterprise Server (deviceside=false) or the carrier's WAP gateway (although this also requires information from the carrier).  This link explains the connection routes available on BlackBerry.
