Any ideas how to solve this? Blackberry is apparently no longer giving any free support for their APIs.
Are the T-Mobile devices pointed to the same MDS server that the cingular ones are pointed to? Does your MDS server have some settings that restricts connections ? I'm not the admin for our MDS server but I can ask ours if he has any suggestions.
