I know this probably seems like the silliest question in the world, but for the life of me (and all the googling you could possibly imagine), I can't find the answer. I know that when I'm on a call and someone sends me an iMessage, it fails over to SMS because . . . well . . . I suppose it's because I'm a call and don't have an "available" data connection, right? Well...does the same thing apply to FaceTime? I'm curious because FaceTime uses WiFi, and I'd THINK that means I still have a cellular data connection available for sending/receiving iMessages, but maybe not. Basically, the question is: If I'm on FaceTime via WiFi, will iMessages fail over to SMS like they do when I'm on a regular phone call? Thanks, all!
