Accidental dialling - calls routed instantly now?

To "accidentally dial" as you describe, you would have had to either perform several steps, or, more likely, not kept your iPhone in a default state where when you're not using it (e.g., about to clean the screen), it would open from a lock state to the home screen.

In other (briefer) words, get out of your apps (especially Phone) when you're done with them. Keep your iPhone in a state such that when you unlock it, it opens to the home screen.

I would think the point would be this:

"I accidentally dial ... How can I prevent this from happening?" The answer is to keep out of the Phone application whenever possible.

I suppose. In the ten years I've used iPhones, it's happened to me perhaps twice, or maybe three times. As you note, the connection does occur very quickly and your caller ID lands on the recipient's list. I have found that to be true for years. But in my case, none of these two or three recipients ever called me back.
