Use Your T-Mobile G1 As A Metal Detector!
Check your calendars, folks. This is not an April Fool’s hoax, the G1 metal detector app really works!
How the heck does it work? According to the smart bods (namely johnkzin) on the Android Guys post, “Could be the compass. Could also be that metal probably has an effect on the EM fields around the device, and thus affects signal strength/etc. of the GSM radio. Therefore, it may just be looking at fluctuations in the signal strength that are somehow easily relatable to proximity of metal interference.”
That was exactly what I was going to say. Awesome app, either way!
