The first is it is talking about connecting to cell phone networks, not WiFi (the best protection against DOS attacks on a wireless network is a baseball bat and a firewall).

How will you locate the device causing the DoS in a WiFi network? If you don't know the location, your baseball bat won't do much (good|harm). Also, a firewall won't do anything to protect against a deauthentication DoS attack on WiFi (which is one of the most efficient, if not the most efficient, DoS attacks known to date).

May I suggest adding a reference to the GPL-licenced software pyrit in the summary? It might be useful for people to know that a) Elcomsoft is not the first to implement this and b) a free software implementation exists (currently only for NVIDIA, but they are planning ATI support).
