I don't think opera mini can download files directly - it seems to send the download link to the N95's built-in browser. However, I have found that when trying to access torrent sites (e.g. mininova.org) one the built-in browser the site is blocked (work ok on Opera) - I'm on Three uk. I think this is the reason that you cannot download .torrent files

. If you wanted to test symtorrent then you could copy a torrent file from your PC to the phone and then open it with symtorrent - I haven't had chance to try this yet but I suspect that if Three are blocking access to torrent sites then they may well block torrent traffic in general so Symtorrent may not work unless there is a way of encrypting the traffic

.
Peace.
