Mogul and Slingbox users

If you ever wanted to lock your device with the SlingPlayer Mobile running
in the foreground instead of the background, there is a way.

Use Settings->Buttons to have one of your buttons start the SlingPlayer
Mobile.

Press the button you have programmed to start the Slingplayer Mobile and
immediately after that tap on the "Device unlocked". It will lock the
device and then Slingplayer will start and run in the foreground.
