For this behavior I wouldn't need in-app billing. I just present the user a dialog to enter the code and if it's correct I make the app a premium version. Therefore the user would need to remember the promo code if he wants to install the app on another device or deinstall/reinstall it.
I need something that remembers that this user unlocked the premium version and will do so for future installs. And I don't want to implement my own web service that stores user accounts that unlocked the premium version.
