I tried
Free Range RSS feeder that I saw suggested over on BH on my HP PPC (also works on phones and Blackberries). It seemed like a great approach because it would download the headline, one more click gives you RSS type partial data and another click would download the entire story and it was very quick. You can set it to download the entire stories on all articles to start withwhich then makes it more like AvantoGo. It's also free. You have to do a bit of looking around on the site for the various downloads and you can modify your feeds on your PC.
The only issue I had was I added some RSS feeds that I use on Newsbreak and even though they downloaded yesterday, today they wouldn't but I'm not sure if my settings were screwed up or there's a problem with the app. My money is that it was a "me" problem
. It might be worth a look.
