How to save emailed video to iPhone camera roll? When I press and hold down on the video I get 3 options: Quick Look, Open in "Polkast", Open In. None of these options will save the video to my camera roll. Thanks.

If you are getting an "Open In" prompt, this means the video is not in an iPhone compatible format. If the video is in an iPhone compatible format, you should have the Save Video selection. There are some 3rd party apps that allow for viewing video received with an email that are not in an iPhone compatible format but this doesn't mean you can save the video to the Camera Roll.
