Will RSS feeds to your mobile really be a killer app? I wonders, seeing most of my family and friends have not a clue what RSS to their PC is yet! But, I have experimented today with 49PM, a java based RSS feeder for cell phones.
You can get the software here and put it on your phone. It works, but whether or not I will bother to fire up a GPRS connection often to check news feeds on a tiny screen is unlikely. Perhaps those with serious SmartPhones or Blackberries etc. may find more use. I canned the default feeds and tried my own, and sure enough they were located and downloaded quite quickly ... but data transfer via GPRS is expensive in South Africa, so this may be a little ahead of its time here.
