No they don't, I have the Diamond (no kb) and they do not. Pics, web, and a couple of others do.
There are programs, Rotation by SK Tools, you can download supposedly to make them do this, but not working on my phone, might not be compatible.
I like the phone, love the screen, size, love Opera, but harder to use than Palm. I'm not big on WinMo, always had to use stylus and I love the easy use big buttons of Palm. TouchFlo is definitely an improvement, big program screen that holds faves to push is cool.
I do like the keyboard, functions great, easier than Palm querty for me to use which surprised me, so wouldn't need Pro kb or size.
However, I'm going back to Centro. I have decided to wait for HD even if it is a year out. Or hopefully Palm will jump on the bandwagon and make full size touch screen, even Blackberry is doing it. Or is this just wishful thinking. . .
