I'm only getting it when I click on the New Posts icon. It gives me a big block of white drop shadow text on a blue background--directly under the Search Results heading.
Edit: This Safari on an iPhone 4.
I'm on android so it's hard to tell what you're seeing. Is there anyway you can send a screenshot to firstname.lastname@example.org
I think you press and hold the bottom button then press the top power button at the same time.
