I have a webservice that when called without specifying a callback will return a JSON string using application/json as the content type.

When a callback is specified it will wrap the JSON string in a callback function, so it's not really valid JSON anymore. My question is, should I serve it as application/javascript in this case or still use application/json?

Use application/javascript. In that way, clients can rely on the content-type without having to manually check whether a response has padding or not.
