Since I have the latest version of AutoDisconnect have on my N900 to my RSS is not automatically updated. I can see how the RSS is trying to set interval to open an internet connection, but it does not work. If I go to manually update it works. Can it be so AutoDisconnect has a bug and I hope it is possible to resolve it.
The drawback of this method is that the connection phase last 3 seconds more than in classic mode. So some of your applications which initiates the internet connection (like OMWeather) could believe to a timeout.
MFE or others softwares doesn't connect automatically if the device is not connected. See Bug 7180
