The iPhone will not "shake hands" with the Samsung Camera Network. Sees network and tries to connect but eventually times out. Failed 100% of my attempts with Remote Viewfinder.
For interest, downloaded Samsung Mobile Link which is designed to allow transfer of images from camera to iPhone over WiFi. Again, fails to connect although after several failed attempts, I did get it to connect once and succesfully transfered my photos from camera to iPhone. At least I know it is "possible" but until the program is modified to allow seamless connection, not useful.
