Notify when connected to working Wi-Fi point I use my phone to receive all my calls over SIP.  Sometimes when I need to make a call I'm not around a (working) access point.  

Let's say, if I'm walking around is there an app that can notify me (via vibrate or ringtone) when I've connected to an access point? So basically whenever SIPdroid lights up green.
