Off-topic, but I always wondered why both on iOS and Android some built-in applications (notably program selection screen) are always portrait-locked?

As a Nokia E70 (Symbian) user, this always buggers me. What if I want to search for something (and for that, use the long-edge keyboard)?

What is the rationale here?

What's the program selection screen?

The one with icons you use to start programs. Probably "main menu."

Ahh! On Android that's called the launcher. The part where you can put widgets and shortcuts is the home screen and where your apps are listed is the app drawer (it literally used to be a drawer.) On iOS it's SpringBoard or home screen.

I can only speak about the former, but If it rotated it would screw up the layout pretty badly as normally the screen is taller than it is wide, so widgets would be truncated and icons wouldn't fit either.
