Tiny, easy to hide and an unmonitored link for convicts to the outside world, cell phones are valuable contraband, fetching a greater asking price from convicts than some shipments of illegal drugs.
More than 1,200 wireless phones have been confiscated from inmates in Texas prisons and from inmates in transit to Texas prisons during 2008.
John Moriarty, inspector general for the Texas Department of Criminal Justice, said that one phone can fetch as much as $2,000.
"It takes one crooked prison worker to populate a whole prison unit with them," he said.
In January legislation was introduced in the state of Texas that would let prisons jam cell-phone signals within their walls.
