Will it detect WEP/WPA encryption, or just blindly tell you if there's something around broadcasting its SSID? And is that tacky badge aesthetically removable?

WiFi scanning watch + Nokia E51 + Truphone = Cheap / Free calls worldwide.

I'm very interested.

On further investigation, it looks quite likely this thing is completely dumb, and just detects how much signal there is floating around in the appropriate frequency band. In practice, it will be an "I'm in a built-up area in a civilised(-ish) country" detector. My eyes are good for that.
