App info is currently processing and/or the app is not yet fully available for sale on the US App Store. I got an AppShopper alert on this. Honestly, I can't remember why I added it to my watch list since I have Camera+ and don't expect that another camera app will ever replace it, but I thought I'd grab it and mention it here since it's the first time it's gone free (according to AppShopper).
OLD POST - no free sale original post Jan 30th = old. got it a month ago. "Andre" bumped it to say its great, so it looked like it was updated/new post.
