That's how IMSI catchers work, your phone joins their network. The network determines the level of encryption, if any. And last I remember there were basically no handsets out there that would even report missing encryption, so I'm not too sure on the iOS 5+ part, but unless you are staring at your screen all the time you would probably miss any such warning anyway.
(Not to mention that A5/1 is broken, but since Stingrays have been around forever and companies don't like investing into something thats not broken, I don't think they even do that. Certainly not at 9k bucks.)
