Fennec has aus2.mozilla.org, while Desktop switched to aus3.mozilla.org prior to Firefox 4. We should also check if the following preferences are set app.update.cert.requireBuiltIn app.update.certs.1.commonName app.update.certs.1.issuerName app.update.certs.2.commonName app.update.certs.2.issuerName to get the CA pinning. There may be other preferences to sync up too. This is all from inspection of mobile/xul/app/mobile.js, and it may pay to do native here too.
