I found this nice video online
and followed it. I go to mypebblefaces.com, select a face, click on download in Safari, but when I tell it to open in pebble app (iPhone 4S most current iOS, non-jailbreak) the pebble app pops open, but does not appear to do anything with the file. The app just sits at the home screen, with the green connection button pulsing. If I ping the watch, I do have a connection.

Help?
