It was Tweetie 2's auto-rotation which pushed me over the edge and into writing 800 words about a telephone.

Not sure I recognise your problem with the iPhone on British trains. Maybe the trains wherever you are move faster than London Midland :-)

It's mainly a problem when standing up on a busy commuter train. Luckily I don't do that much.

Tweetie 2 is one of the few apps with reasonably robust settings exposed to turn off or selectively use auto rotation.
