I'm running the O2 box with beta firmware 10.2.2.9.BF_RC3 and it has a guest WLAN that can be enabled through the GUI. I imagine this is what the OP is referring to.
It's not simply another admin/non-admin account. It is another ssid with it's associated password using a different subnet.
I'm not sure if this was available in the standard firmware although it was certainly possible to do through Telnet.
