All, I'm new to the Phantom 3 so please excuse my basic questions. I recently purchased a P3 advanced and am just now getting around to trying to get it set up and running. I have an iphone 6s and just downloaded the DJI GO app. First question: with the device holder on the remote, am I only able to hold my iphone vertically? I would really like to have it set horizontally to take advantage of the wide view. Second question: am I missing a cable or do I just take my 6s charging cable and use that as the link between the controller and the phone? Finally, is the link between the controller and the phone needed to pick up the WiFi signal? I just ask because as I'm sitting here (w/out my cable) I'm trying to get my iphone to find the P3 WiFi signal and I'm coming up empty. Thanks for any advice.
