I can see why they wouldn't think of it in the first version of the iPhone, or the first couple of releases of iOS. But now it's way past the point where they surely have thought of it. Nearly every default app does landscape. Mail, messages, calculator, etc. etc. The iPad does it. Why not the iPhone? Why is it that I have to turn my phone sideways, and hit the messages app all disoriented just so I can text in landscape? Ditto for mail or any other app I want to open in landscape. Not a HUGE issue by any means, yet something that seems so simple and intuitive to have.
