Do you mean this as in "it's not officially supported", "it's not our primary/initial concern" or "it won't work"? I understand the purpose of Qt Mobility and Qt in general, in terms of portability, but Qt+extensions can't cover everything. Specifically, the work I'm doing at my university involves a couple of libraries developed independently by members of our team (this, for one), and I'd be a bit concerned if the new SDK is designed in such a way that using those will be painful.
