I have received a small number of emails from customers having troubles with the Apple login UI popping up even though AutoWiFi is installed or AutoWiFi claiming there to be “no wifi connection” when running OS 4.1. This does not occur on every device (in fact it does not occur on any of mine) however I am in contact with Apple about this issue, once I have more information from Apple this post will be updated.
Update:
If you rely on AutoWiFi please do not update to OS 4.1, you run the high risk of AutoWiFi no longer working. Apple has confirmed the issue and is investigating it internally. More updates will follow once I have more information.

I know few of the users and all of them find AutoWiFi useless with new IPhone. It just does not work!
