Hey, I was wondering if there's a jailbreak substrate add-on that makes an iPhone/iPod check for an available and working (test packet send and receive) WiFi whenever it is disconnected from WiFi and attempt to connect with that WiFi router. For example, if I walk with my iPhone to a library I've never been to before, my iPhone will automatically connect to any public WiFi available there. Just curious if it exists and if you can point me to that app.
