Other prisoners at Welikada also seem to take their cell phones seriously. In November, at least 27 people were killed when prisoners rioted during a search for illegal phones and drugs, reports Reuters.

Apparently, Brazilian prisoners are pretty passionate about their phone, as well. In January, a prisoner apparently tried to smuggle in a cell phone, earphone, memory card, charge, drill and saw on the back of a cat. According to Reuters, the hapless, duct-taped feline was "detained" by authorities, who quoted a prison spokesperson as saying, "It's tough to find out who's responsible for the action as the cat doesn't speak."

In the U.S., while it is a crime to possess a cell phone in federal prison, illegal phone seizures have increased dramatically, according to the Washington Post. But this has not prevented prisoners from attempting to smuggle phones in their "privater" areas. Gizmodo got the scoop from a Sergeant Don McGraw of California's San Quentin State Prison. According to the Sergeant, inmates often use bathrooms as a way to pass phones from friends on the outside to inmates:

"An inmate's associate on the outside will have taped a package (of phones, drugs, tobacco, etc.) to the back of the women's toilet, for example," said the Sergeant. "When the inmates come to clean, they toss it in with the rest of the trash, then sort through it later. Then, when when nobody's looking, whoop, up the butt it goes."
