http://www.mulliner.org/blog/blosxom.cgi ...stuff I do and things I like... en Fri, 14 Aug 2009 19:22:00 GMT http://www.mulliner.org/blog/blosxom.cgi/2009/08/14#cellconmon <a href="http://www.cyrket.com/package/org.mulliner.cellconmon">CellConMon</a> is a simple mobile phone network connectivity monitor that tells you when you lose and re-gain connectivity with the mobile phone network (GSM/3G). The application just uses the notification bar and the LEDs to notify you about connectivity changes. There is no application or GUI. <br><br> I created the tool as a countermeasure for our SMS-based Denial-of-Service attack where we can knock Android phones of the network. The tool will notify (notification bar massage and RED blinking LED) you if you lose connectivity. I also found it to be useful in normal (not being attacked) situations where you lose connectivity due to being underground or whatever. <br><br> The tool is in the Market but can also be downloaded from my Android <a href="/android">page</a>.
