where is the setting that causes an iphone mail message to turn sideways (when you turn the phone 90 degrees?) It used to work, but now it doesn't.
Quick question, is it all screens that wont turn sideways or is it just mail?
If it is all screens check this out.
iOS: Screen does not rotate
If that isn't the issue try doinga two button reset on your phone by pressing and holding the sleep/wake button (power button) and home button until the phone shuts off.
