Cell phones jammed during VT shooting?

There is much more to this story that is bieng let on. Seems that the administration with local officials shut down all cell phones on campus. I am trying to find any other information on this. The other part is that a bomb threat was called in that day.

While there appears to be growing criticism over law enforcement's handling of the events that unfolded Monday at Virginia Tech, they should be commended for covering a number of other potential scenarios that nightmares are made of in this post 9/11 society.

According to a law enforcement source speaking to this investigator this morning, authorities were very concerned that improvised explosive devices were planted at the Virginia Tech campus prior to the shooting by the killer that they used a tool that is frequently employed in Iraq - a device that jams radio signals, including those used by cellular telephones. The tool, known as Warlock Blue, jams radio frequencies intended to detonate hidden, remotely detonated "improvised explosive devices" or IEDs that are often triggered by cell phones, garage-door openers and similar radio controlled devices. The countermeasure could have also prevented any communications between perpetrators if others were involved, added this source.

So it seems that the bomb threat was the day of the shootings. Was this because the shooter knew that the cell phones would be jammed and if started shooting, it could not be reported. This guy seems calculating enough to research this, know it and do it.

A shooting and a bomb threat seems enough to institute a lock down. Can anyone verify that this occured? I have read varied reports of some students not being able to use phones and wonder if this is why.

The shift to the Internet came as cell phone networks were stressed during the crisis. Verizon Wireless, the second-biggest U.S. wireless carrier, said it saw four times normal call volume, peaking around midday, hours after the shooting.

Seems they moved to the Internet because phones were 'overloaded'.
