How do I get the precise location (house/address)....

Of a cellphone number? Using open source methods (google etc).

1) Call the number
2) Ask ``What is your precise location (house/address)?''
3a) Note to yourself that Google's primary service, a search engine, is decidedly not open-source.
3b) Note that were there not a moral restriction on a certain redirection, it would certainly be in play.

First get the name of the person. Then call the number and

- Hi [person's name], I'm [fake name] from [company], we believe there's been a fraud with your credit card; could you confirm your identity by telling me your full name and address?

This only works on total morons though, so there's a 5% chance it won't work. 1% if you're in the USA.

Google's primary service is advertising, you lackwit.

Good point. That it's not open source still stands.

Call the NSA, tell them you wish to track a cellphone number. They'll be happy to comply, all they do is track their cheating spouses, anyway.

Constantly call the number, walking around the city with the matching area code until you find them. If they are not at their house, stalk them.

May be easier to hire a private detective.

all jokes aside, it would be interesting if this could be done using the proper hardware.

1. Intercept cell phone waves
2. Crack all encryption and listen to all near cell calls
3. Call phone number and initiate a conversation.
4. While conversing, have instruments locate the strongest direction of the source and calculate signal strength.
5. Repeat from multiple locations until triangulated.

You know cell phones don't transmit data directly between each other, right?

What if one of them sets up an adhoc wifi AP?

Then it's not Android, and iOS can only connect to an existing adhoc, it can't create the network.
