All I can say is that on my three test devices I'm unable to get them to autoconnect to a karma'd SSID. I have an Android phone (2.3.6), an Android tablet (4.0.3), and a Windows laptop. All of them have saved unsecure networks saved that they will autoconnect to when they get in range. No matter what I do I can't get them to autoconnect to the Pineapple. Some people do get connected though, I just can't replicate it.
