I finally decided this morning to make Instacast free. There are a couple of reasons why, but mainly because I don't have the time anymore to really push the project forward. However, I know that there are a couple of die hard users that still really like it and I feel that I should be able to at least maintain it and keep it working. That's not the case however. That's why I am also making the source code of Instacast open source today, in the hope that the community takes over and keeps Instacast compatible with new versions of iOS and new devices. That would be wonderful. Otherwise, at some point I would have to remove it from the App Store.
You can find the whole source code over on GitHub. I will do my best to test and accept patches in a timely manner and from time to time publish new releases to the App Store.
