I am not aware of anything being written up in detail for prisons. Prison life in general in 2072 SUCKS, however. If it is a corporate prison you have no legal right of any kind. You are entirely at the mercy of the corp. Not good.
A UCAS or CSA prison might be a little better, but not much. Convicted of a crime you have a criminal SIN, and you are basically sent off to a metahuman warehouse to degenerate into base savagery, tribal alliances, and sodomy festivals. Abuse, neglect, violence, crime, terror, and brutality would be the order of the day. Anyone with useful cyberware (anything that makes you in any way better at fighting a guard, planning an escape, contacting the outside world) would be disabled or removed. Cyberlimbs would be modified to as to give no extra strength, agility, etc. Cyberweapons would be absolutely ripped out before you hit the general population. Armor/dermal mods might be removed as well, and headware is likely to be at least inhibited or deactivated even if they don't go in there and dig it out of your nervous system.
Awakened prisoners will likely have it even worse. Anyone who can summon a fire elemental or control someone's actions is either going to be subjected to extreme anti-magic protocols, if not simply put in hot sleep and kept on a shelf.
I don't even want to tell you what they do to the technomancers if they find out you have emerged. You wouldn't sleep at night.
I am not saying that a prison campaign can't work, but it would take alot of work to pull it off, the players would have to really be on board. I would think maybe opening a campaign with a prison break adventure, but spending the whole game in a prison would get nasty and depressing after a while. I don't think its a game I would want to play in.
