Summary:

Even when UIRequiresPersistentWifi is enabled, iOS 5.1 loses Wifi connection after 30 minutes.

Steps to Reproduce:

1. get a clean iOS5.1 install, so no other app keeps the connection on in the background.
2. Run an App with UIRequiresPersistentWifi and [[UIApplication sharedApplication] setIdleTimerDisabled:YES] longer than 30 minutes. Results are reproducible on an iPad/3G.

Expected Results:
The Wifi connection stays on.

Actual Results:
The wifi connection drops off after 30 minutes. If there's no 3G, the internet connection is lost.

Regression:

Notes:
As we do an App that could run for hours and needs connectivity this is critical.
