Hello! right now the iOS variant does _only_ support upload of an "Development SSL Certificate" (see [1]). I'd like to add support for an "Production SSL Certificate" to the iOS Variant model class. Besides the second certificate, the model class _should_ have a field to reflect the status (is production or not -> isProduction()), so that only one certificate is ACTIVE. Internally the "Sender API" would connect against the differen Apple servers (prod. verus dev), based on the value of the isProduction() method. Exposing "production" (or "development") on the Sender API would be really ugly. With the above said, the Sender-API remains stable. The value of "isProduction" would be updateable on the AdminUI (and the underlying RESTful endpoints). -Matthias [1] https://github.com/aerogear/aerogear-unified-push-server/blob/master/src/... -- Matthias Wessendorf blog: http://matthiaswessendorf.wordpress.com/ sessions: http://www.slideshare.net/mwessendorf twitter: http://twitter.com/mwessendorf
