I'm sorry, Neil, but I cannot agree with you. This is not the way that things work in the debian world, Maemo being a debian variant. This is going to confuse users and readers of this forum, as anyone can find the repository through a search in the threads, and anyone is able to add the repository to the app manager. As already said, though I could be wrong, debian policies do not allow for "incremental" updates. Every update to the available deb must contain the full application with all files, not just those "new" files. Anyway, if this incremental update is the way Sygics wants to follow, then the debian package should have been marked with a dependency on the first package, that one from their site only available to buyers, so users like me cannot install the update from App manager. It's the first time I found this kind of app deployment in the debian world, and due to it Sygic could be loosing customers which install an app that simply crashes without even a visual warning. Or Sygic should make the full app available through the app manager and then deploy some activation key for buyers to activate it. Just my 2 cents.
