The first time I started my Nexus, I got a welcome screen. Among other things it allowed me to create a message that scrolls across the screen when it is 'locked' (a screen with the time and a keypad that allows me to enter a numeric password). I would like to change that message, but I can't figure out how to access it.

TIA,
Anthony Parker

does this mean it is not easy to find? I need a command line to see ipconfig?
I too want to turn on the added security for my wireless network.

Ok, with the linksys, I was able to turn off MAC filter then look in my router for the connected devices. The Nexus was the only android device and its mac address was listed. What a pain, why can't the nexus tel me its mac address?
