I don't believe it's a two way trust, since the "MAIN" domain is the authentication domain, while the DEV/TODEV domains contain their own resources but the MAIN domain does not trust users in the DEV/TODEV domains.

As I say, it works with DEV, if I run wbinfo -r jlewis, I can see my group memberships in DEV, but not TODEV.
