To add a cert to the BES:
This info can be found in the Admin Guide. Although I am not sure it will help.
1.Copy the certificate from a secure web site to a .cer file.
2.Copy the certificate file into the j2re1.4.2\lib\security folder on the computer on which the Mobile Data Service is installed.
3.Import the certificate into the key store using the keytool, which is installed in the JRE bin folder, (typically, <drive:>\Program Files\Java\j2re1.4.2\bin). For example, type keytool -import -trustcacerts -alias <alias_name> -file <cert_filename> -keystore cacerts.
4.Type the key store password.
5.At the Trust this certificate prompt, click Yes. The certificate is added to the key store.
