Wi-Fi sleep policy when mobile networks are turned off I have a fairly expensive data plan and I don't want my phone to use any of it, so it turned off mobile networks in Settings. When I access the Wi-Fi sleep policy setting, it says it switches to mobile networks when wifi sleeps.

Is that really the case? Does wifi sleep policy override the setting that disabled mobile networks, and eventually use them?
According to my experience, it does not turn mobile networking on. I have Android 2.2 on HTC Desire HD.
