I don't seem able to download anything from within app mgr or using apt-get install. I can't download any feeds using feedingit. I can't download any books.
Maybe the application manager isn't using the proxy settings? I haven't tried proxy on the N900 (no privoxy package afaict.. which is what I used with the older tablet) so I don't know.
I'm not using privoxy; what appeals to me in using this tor package is that I don't need privoxy.
I mentioned that Feedingit doesn't work for me when I use Tor and tmobile, but I have since discovered that the default rss program does work for me. But I also found that Feed Circuit doesn't work, so two out of three rss packages don't work for me. Interesting clue.
