Well basicly what ovi store does in that case is that it just sends an SMS with a download link to the application. Therefore to download you would require a dataplan of some kind.

Well in theory it could work with MMS but you need a customized application to send other attachments. Don't know if fMMS will try to achieve this. But I wouldn't count for this to work.

I'd say that bluetooth is the only way to go then.
