I'm trying to text my wife video taken on my iPhone 4. When took the video and saved it to my pictures then sent it out, she couldn't even open it. The text she received was a blue square with a play arrow on it and she received an error message when she clicked on it. I also tried to take video directly within the text application. This time she received the video, but it's very very compressed and pixelated. Are iPhone 4 vids not compatible with 3G? Can you only share quality vids with other iPhone 4 users? Major bummer if that is the case. Anyone else having this problem, have a solution or explanation? Thanks.
