From what I read on the prison site (IMSI) the iPads are not free. Nor are TV's standard (but maybe can be purchased?) They have really limited internet and email access.
In BK's category of prisoner, his correspondents need to be approved by a prison manager. If the people messaging him are not immediate family, the Director of the whole prison has to okay the communication (which would then include visiting the prisoner in a no touch setting).
It's interesting to find tours of IMSI online (or reviews). It's a grim place with few perks. Commissary expenditures above a certain amount must also be approved. Apparently, everyone who is not on Death Row works a solid 40 hour work week. The cells I saw in one video do not have windows or bars on the doors - the bars are behind a steel door, so the person inside cannot see out until they are allowed out of their cells. These are not considered "solitary" confinement as they come out of their cells under guard to get exercise in groups, eat meals, shower, etc.
Then, they have these teeny containment cells for really out of control prisoners (they're not supposed to keep them there for more than a certain amount of time, as written in Idaho's policies for prisons). Those are true solitary confinement. Really grim spaces. No iPads, no TV if prisoners are not well behaved. They can start accessing those perks after six months, IIRC.
The policies are extensive and contained at that link. Not allowed to link to the youtubes, but IMSI has a few things one can find that show the inside.
