Connect Using a Certificate

You can set certificate information in ConnectionProfile.

ConnectionProfile profile = <PkgName>DB.getSynchronizationProfile();
profile.setDomainName( "default" );        
profile.setServerName( "host-name" );
profile.setPortNumber( 2481 );
profile.setNetworkProtocol( "https" );

Install the certificate to BlackBerry:

Simulator: copy the certificate to the simulator directory.
Physical device: use the Desktop Manager Certificate Synchronization tool to import an HTTPS public certificate from the PC to the device. Then perform a synchronization with Unwired Server by HTTPS.
