Internet Access in the Jails: Why it's a problem

Quite rapidly, smart phones are making their way into the prison, which means Internet access for the inmates. One prisoner at a Georgia state prison marks down the days until his release via his Facebook page. Other inmates, including himself, take the time to play FarmVille and other Facebook games. The same prisoner who marks down the days also happened to organize and coordinate a small strike among the inmates at multiple prisons in Georgia.
If you think about it, this really isn't all that surprising. Even Martin F. Horn, "a former commissioner of the New York City Department of Correction" admits that "This kind of thing was bound to happen...The physical boundaries that we thought protected us no longer work."
While one may assume that Internet access will keep the prisoners occupied, one also has to assume that these prisoners will not always be using their time to play online games. Internet access will allow prisoners to "call up phone directories, maps and photographs for criminal purposes," according to prison officials. In other words, the criminals will just keep on being criminals. On extreme levels, one may even say that they'll be able to plan something big while in prison, only to have it actually carried out beyond their cell walls.
Instead of a knife or other kind of blade, Terry L. Bittner, the director of security products with the ITT Corporation, claims that "The smartphone is the most lethal weapon you can get inside a prison." This poses as a major problem for the guards and for the prison directors because these phones are smuggled in all the time and if they are not all confiscated, a major (illegal) event may occur.
One of the inmates at Smith State Prison in Georgia said that, "Almost everybody has a phone. Almost every phone is a smartphone. Almost everybody with a smartphone has a Facebook." Using pseudonyms for confidentiality, prisoners are able to easily contact one another, while allows them to plan strikes and protests, as well as overall encourage criminal behavior.
In 2009, a few Maryland prisoners were caught approving targets for potential robberies via their smartphones. Some prisoners even try to order products from the outside, such as seafood and cigars (those wouldn't be my first choices, but, you know, whatever works).
From January 2010 to April of the same year, the Federal Bureau of Prisons workers collected 1,188 cellphones. In California, 9,000 phones were confiscated throughout 2010. While there are metal detectors and X-ray machines available, some smugglers even try to throw the phones over the fences so that they can collect them once they're in the clear. Jon Ozmint, director of the South Carolina Department of Corrections, says that some of the way phones make it into the prisons is that smugglers "stuff smartphones into footballs or launch them from a device called a potato cannon or spud gun, which shoots a projectile through a pipe. Packages are sometimes camouflaged with a coating of grass, which makes them hard for guards to detect."
So I guess the following questions remain: Will prisons ever be able to prevent or stop these phones from getting into the cells and into the hands of prisoners? What can/should the prisons do to try to prevent this?
