In more modern cities it's (thankfully) getting to the stage where it's more uncommon not to find Wi-Fi in a restaurant or a bar, but that's not the everywhere – and in remote places where cellular data is scarce, Wi-Fi becomes even more valuable.

Facebook isn't your only option, as a number of apps and services can already help you hunt Wi-Fi – the problem is getting the data on who offers it and who doesn't, so we'll see if Facebook's vast reach helps. Of course you can always just go inside a place and ask as well.

Updates for iOS and Android being pushed out now, and once you've got the feature, you can find it clicking on the More tab inside the app and then choosing Find Wi-Fi from the list. Happy internet hunting – just remember public Wi-Fi is inherently less secure than your home network.
