This has been driving me crazy a little. Is it Camera Dot? Camera Interpunct? Camera Bullet? Camera Middle Dot? Camera Diacritical Character?
But I think, maybe, just "Facebook Camera" is the name they'd choose.
Glad they changed the name, though...am assuming Apple made them change it (which makes "interpunct" kind of hilarious); was totally surprised that it made it through to begin with--an identical icon with a different background color & the same name, many users wouldn't know the difference...and "Camera Interpunct? Dot?" is way better than "Camera - I don't know what happened, but my camera is broken and it always goes to Facebook!"
