Appreciate this isn't what you're asking for but rather an additional tip - download 'The Cloud' from the Play Store: https://play.google.com/store/apps/details?id=net.thecloud.fastconnect&hl=en_GB - while it won't give you universal coverage, a huge number of local coffee shops, cafes, etc, all use The Cloud to offer their customers free wifi. I can't remember how I did it but there's an option in there somewhere to automatically connect to ther network when in range - might save you a few £ which could otherwise be spent on precious, precious beer.
thanks. android version https://play.google.com/store/apps/details?id=net.thecloud.fastconnect
