I occasionally go to Wi-Fi hotspots when I'm not at home and I was wondering is there a way I can use my iPhone for example to locate the source of the signals?

You mean locating the hotspot that you are connected to? There should be lots of application that will tell you the signal strength from that you can locate the wireless AP.

I use WIFI Analyzer on my Android phone.
