Not sure. When you pass the beta, they email you (after quite a while) and tell you to log-on to your Prometric account, and make sure your mailing address is correct, as they will send you your certificate etc. within 8 weeks of the pass being announced. Considering you took your exam 3 months before one of the exams I have been told I passed, I am guessing the beta is closed and results announced.
Is there anyone you can contact at your old company to see whether Prometric sent you anything at that address?
I am sure there is a way to verify results via Prometric and/or RIM, but I have never looked into it.
