Well I’ll be damned, someone has actually done it!
A fully featured bittorrent client for your s60 mobile!
I am giving this a go on my N95 8GB now!
UPDATE: This works well by the looks of things.
DISCLAIMER: I AM USING WIFI FOR TORRENTS, DO NOT USE YOUR GPRS / 3G / EDGE DATA SERVICE FOR TORRENTS UNLESS YOU WANT A HUGE BILL!
