There are quite a few wifi sniffers for Android, just search for
sniffer or
network in the Play Store.
I've used them to send and receive emails while traveling. Found a hotspot at a touristy temple in New Delhi (evidently from the business office inside), and others in various street locations in Rome, Dubrovnik and Lisbon.
