You may be able to download a torrent using BitLet - the BitTorrent Applet. It is a website that lets you run torrents through your browser. I have used it on friends computers who don't have or want a Bit Torrent client., but not on my BB. Worst case scenario: it doesn't work.
going to be harder and harder with the US anti piracy laws and shutting down the big companies now... first mega upload and I hard a couple more yesterday?
Yes, i recently downloaded a very underdeveloped one for my 9900. MobTorrent. It's currently on ver 1.1 with what seems to be a dropped project. Not sure how it'll run on a 9810 though. It comes in a .jar file which can be installed.
