[android-developers] Re: Request for Ideas: how to handle a major upgrade to my App

Interesting, hadn't thought of in-app purchases.

That may work as well because I currently have a Free version of the
app and two separate Paid versions (all build from the same codebase
though). Having an In-App purchase would be neat.

There is a downside though: the paid version of my app is very highly
rated because the folks who buy it (generally) understand what it is
for and how to use it...the ratings for the Free version suffer from
the normal idiot pollution that affects many free apps.

Will need to think about that.
