There is new firmware for the GoPro Hero 3 cameras and a new app. With these you now can watch video recorded on your GoPro via WiFi on your smartphone or tablet. In video playback mode you can only watch a low res version of the footage but its a great feature making it really easy to check a shot back straight after the shoot to make sure all went well.
You can also view stills taken with your GoPro via your smartphone or tablet. With Stills you get a reasonable high res image version.
You can also save video or stills directly to your smartphone or tablet and even share these immediately with social networks.
I love these updates, they make a great camera even better!
