These are definately linked to Google Voice. I have had GV installed for only 3 days. No other Google apps installed, and I have seen the same certificate issue for the past 2 mornings. I clicked trust this am, so we will see how that works out tomorrow am.
It's been doing it to me too. I got the same IT policy what-not message when I tried to trust it which is weird since I am the original owner and it's been strictly for personal use. I don't even know of any local companies that use them on a BES.
And it's been popping up at random times. I usually see it after I've unlocked my phone though, not while I'm in the middle of something.
On T-Mobile with BES and BIS on 2 different Blackberries. Google search app, Voice, and Maps installed.
IT Policy won't allow the cert to be trusted. Sync of Certs via DM didn't seem to help for long (maybe if someone could find the cert root for download, it could be fixed).
My Google cert was at the end of the list, ordered as a "w" with "www.google.com" not in the "g's".
I did it, including the Fetch Status step, and it seemed to work. On the 9700 with OS 5.0.0.423, the menu is Options/ Security Options / Advanced Security Options / Certificates.
I was able to trust the Certificate by going to Option - Security Options - Advanced Security - Certificates and changing it there. Instead of having a check mark or 'x' by it, it now has a question mark.
