Hi Greg,
Thanks for the question. I've seen iPhone devs do this differently. I, along with most, will support their product with free updates for the life of the software. So if the next release is iLinc 2.0 it would be a free update for those that purchased version 1.0.
Other devs might have the users buy version 1.0 and then release a seperate app with upgraded features and call it 2.0, forcing the users to buy it twice with the upgraded features.
All updates work through the App store on the iPhone or Touch. When you log into the App store on your device, the App store looks at your installed apps and then notifies you that some of your installed apps have updates. Once you acknowledge the updates, the App store app will automaticially download the updates and install them to your device.
In the upcoming 3.0 OS update this summer, Apple is introducing in-App transactions. Imagine a newspaper or magazine app. The app is only the shell; the user can then buy a subscription or individual magazines from inside the newspaper or magazine app.
I hope this answers your question.
