No BIS contact sync
 

Problem: My contacts added to my BB 9780 in the last few weeks (at least) do not sync to my Gmail contacts. Contacts added to Gmail do sync to my BB.

I don't really know how long this has been going on, but it's at least two weeks. I only discovered it by accident, searching Gmail for a contact that I knew should be there, but wasn't. It's on my BB, however. The problem was probably there for weeks before I noticed it.

OS: beta 6.0.0.526, but only for a few days. Before that I had .480.

What I've tried:

1. Checked in Mail>Options>Email Account Management to be sure that Contact sync was selected.

2. Checked in Contacts>Options that there was just the one Gmail account.

3. Re-sent service books.

4. Did several battery pulls at various points.

5. Called T-Mobile. They had no idea what to do, beyond sending the service books again.

6. Deleted the email account and added it again.

Anything else I should try?

Calendar sync and deleted email sync is working.
