Ta-da is free, and I'm not expecting much in the way of support, but I did write to them

I haven't changed the user agent string, at least not that I know of. After your suggestions, I did in fact dig around and find the iPhone emulation string, and tried it, since tada has just added specific support for the iphone. Works like a charm with tada, and looks gorgeous, but still has exactly the same problem: If I explicitly add the .html extension, I'm taken to the correct live page; otherwise I get an RSS feed.

Anyone know of a user agent string that will force microb to read no extension as .html?

Meanwhile, I'm gonna load the Firefox on the pc and see what it does.

BTW, if you haven't tried the iPhone string, it's pretty cool. Google mail becomes much more useable.
