Number 360 can evoke a lot of feelings but in this case, it refers to 360 Facebook photos. It means that Facebook app have new function. Your phone might have similar app in your camera. However, this is primarily for taking a photo and then sharing with other people on your wall. Seems like promising idea but there are few issues. Frist of all it is not 360-degree photo. It is panorama shot for sure. But to 360 it has a lot to catch up. Also, we found out that pictures are not as great as you would like. Your camera app has probably better. And in the end, we tried few times and we could not upload this photo up to Facebook. Which is whole point. But wait few weeks Facebook will improve and then you will be able to put it on cover photo as well.
