Do you mean wirelessly to icloud. Does that do a complete image?
Yep, wirelessly to the cloud. It's a complete image, although I would think they only upload changes. It's literally a mirror image, you get a new phone and restore it and you would have no idea at all that it was restored. That incredible ease of recovering your phone information, setup, etc is one reason why Apple is so strong. Mind you I don't use an iPhone, I just highly admire their recovery process and wonder why slacker Google doesn't implement something like it.
