I have an application to deploy to Symbian and I am using Qt. It is complete in its core functions and will work overall but there are still functionalities I want to put in that will take me a bit longer to apply. I want to deploy this application now but want to make it possible to send updates to the app in the future, for people who have already paid for the app. What methods are there in Qt to do this. I have been reading from the book Qt for Symbian and looking through Forum Nokia but haven't found anything concrete. Is there any way to do this?
