Rss Feeds For Sony Ericsson Phones

Hi,

please i use a sony ericsson w850i mobile phone. i have an rss reader installed and i want to know if u guys have any feeds i can insert or a website that has several feeds. but i noticed that when i went to a website and copied the link to a feed and put it on my mobile it says cannot find feed. so is there anyone who uses an ericsson phone that knows  how to put feeds or has several feed links on sports,music,news etc.
