I'm confused about the wifi feature on the OM-D, how to turn it on, and its capabilities. I've gone through the menus on the camera, and haven't found an option to turn it on. The manual also doesn't have any "wifi" or "wi-fi" mentions, and only "wireless" is for the wireless remote. Google searches come up with plenty of passing mentions of the existence of the feature in reviews, but no instructions on how to use it. I'd like the ability to transfer photos from my OM-D to my Android phone, mainly for easy sharing and collages. But it's unclear whether I need an EyeFi card, or if OM-D's wifi can transfer files without it? So, where can I find a how-to on OM-D's wifi capabilities?
