One netgear open and another netgear WEP 
I don't know anything about unsecured BTFon and BT-Wifi though - is that a serious issue?
Well basically. The homehub comes up as BTHomeHub-whatever with WPA encryption. The homehub also broadcasts BTFon and BT-Wifi. It basically allows me to use the neighbours BTHomeHub internet if I pay a small fee. I have to enter my bank details to get access usually. Anything I do via BTFon / BTWifi isn't the owners responsibility as far as I know.
My laptop wont connect for some reason but anyway here's the landing page on my phone

It's quite expensive, £3 an hour, £5 a day and £15 for 5 days.
30 days is £39
EDIT: if you are a BT broadband customer and also share your Wifi via BTWifi and Fon you get free access to the service. So basically wherever someone has BTHomehub you can get online for free (which is most urban places).
