I could not get my iPhone 5 to connect to the 6D's wireless network, even though my iPad 2 would connect. I tried a variety of things to establish the connection, including contacting Canon Support, and was very frustrated. I thought, perhaps some other app on the iPhone was interfering, and I even considered resetting the iPhone to factory settings to test that hypothesis. But it was going to be a horrendous task to then re-establish all my apps, etc. I continued to do a lot of experimenting and eventually found a solution. Now I can connect my iPhone to the 6D's wireless network and use the Canon EOS Remote App on my iOS device. If you are also having a problem establishing this connection, try the steps I posted here: http://www.tripodclamps.com/2013/02/26/canon-6d-and-wireless-connection-to-an-iphone/
