Well that's just wrong lol. At least the first three points. Can't say much about cellular, since 3G is dead here. Disallowing of TCB tampering is to be expected, you don't really need that most of the times. Even commercial apps would need Nokia's review for that. There is a Linux-only S^3 toolchain and you can test yourself that just works (well at least the first 3 points). As for permission dialogs in particular, there is no facility, at least not in S^3 and above to display any kind of runtime permission dialogs. Maybe you're thinking of some other OS that isn't Symbian. Furthermore, there is no mechanism for app ownership of files outside of app directories either. And writing to common fs directories is definitely allowed for self-signed apps that specify an appropriate permission. Overall, I sense you don't like being wrong, but you are not wrong, you're just talking about some other non-Symbian OS I don't really know, so I can't really say much about that…
