I have a Blackberry Curve and I use the browser that is supplied with it. It does not translate websites very well, but the .mobi sites work great. I check Fox News and a local news channel everyday and they're both the .mobi versions of their sites. Basically, they are stripped of all styling and they give me a list of links to articles. Pretty straightforward. I like it. I would love an iPhone, but I have to use Verizon and as I'm sure you know, they do not have it.
Anyway, when I visit sites like this one (KS) and others, I get frustrated because I have to scroll down through a bunch of styled divs just to get to the content.
