There is a small problem with the CKeditor when using Mobile Safari. In this box now, the editor is not showing and it just looks like a standard textarea. However when submitting, all the line breaks are removed.
I'm guessing that I am just submitting in "source" mode or something? When the editor doesn't load, it should default to the regular textarea, that does not ignore line breaks.
testing adding explicit HTML line breaks...
EDIT: also, the textarea doesn't even appear in Opera Mini on iPhone. It just shows the brown box with Bold/Italic/Underline etc, written as text not icons.
