There’s one very neat new feature that will come to every iPhone and iPad 2 with iOS 5: a free remote cable release. According to Brian Sweet of the Cult of Mac blog, the volume button on the iPhone’s headphone cord works just as well as the volume button on the iPhone when it comes to triggering the camera app. This means you can stick the iPhone on one of many, many tripods or stands and snap a blur-free shot. It’s a shame that you can’t control the shutter speed manually for proper long, low light shots as you can with a real camera, but we’ll settle for what we can get — bear in mind that any camera made in the last 10-15 years requires an expensive, proprietary remote to do this, whether by cable or IR. And remember, this volume-button trick works for shooting video, too.
