If you're traveling in a foreign country and you're looking to hook up your iPhone or iPad to a nearby WiFI hotspot, it seems that an app for the iPhone called 4sqwifi will attempt to fetch you the passwords of password-protected WiFi hotspots that are within the vicinity. We're sure that there are plenty of us who have attempted to search for local WiFi hotspots while on the go. Not only does WiFi eat up less battery than 3G, but it will also help curb data consumption, especially for those who are traveling in foreign countries and would like to avoid paying exorbitant data roaming fees.
