WiFi Signal Strength
I'm building a personal (not app store) app to collect WiFi data from various places around my building. I have a map of the building, and tapping an area would record the current signal strength.
NOTE: I may not be connected to the network, but will always have its SSID (simply, "Wireless")
I know it's possible since WiFinders in the app store do it, and I want to implement this simple feature (I don't even care about connecting, etc, I just want strength)
