i tried out a friend's iPhone today (incidentally, he doesn't really like it and bought an old Sony Ericsson P900 (?) recently. That's his all time favourite phone).

I was playing around and noticed that I couldn't view the screen all the time while wearing sunglasses. I've never had this problem with angles on the N900. Anyway that as an aside, I was trying to flip between portrait and landscape mode.

The main home screens don't have landscape view as far as I could tell, and some applications, such as the Calendar, didn't either. The main rotateable applications that were there were photos, music player, calculator, internet browser. He has hardly bought any apps so it is quite bare.

Anyway, I'm sure soe iPhone users can let me/us know which parts are rotateable and which are not.

Anyway, many people want portrait ode for the N900 an similarly I would say some things don't need any orientation change, while other applicatios will find it very useful with the option available.
