FWIW, I didn't lose my camera roll, but it opted to once again jumble the hell out of the order of them. HIGHLY irritating. The last ones displaying now are pics I took more than a month ago; the ones I took yesterday or the day before are way the heck up in the list, scattered willy-nilly among older photos. This happened once before, maybe a week or so after I got the iP4, but that time it just took a chunk of about the most recent 50-some photos and moved them up in the list as a unit (e.g. if the pics are pages in a book, then it took the whole book and moved it on the bookshelf last time. This time, it basically ripped pages from the book and flung them around the room.) Grrrr.
