I upgraded my iPhone 4 from 4.1 to 4.2 to see if they made any changes to orientation control on it. No dice. It still lets you lock it into Portrait orientation, or, leave it unlocked. No option to lock it into Landscape mode. Very annoying. Some websites and apps just work better in Landscape mode. Don't understand why it's so hard for them to allow that. Why only Portrait and not Landscape?
