I've had the same issue(maybe) about my widget app. If device goes sleep, my widget couldn't get data from internet whether wake-lock uses or not. So I set "Wi-Fi sleep policy" to "Never", I got data appropriately while device is sleeping. Since I published that app to Android Market, I didn't get any complaints from users. BUT this is not underlying solution, sorry...
