Bill Cosby's been locked up for a week ... and we've learned he spends his days getting friendly with prison staff, touring the grounds and chatting with his wife.
Cosby was locked up last Tuesday for 3 to 10 years, and is awaiting entry into general population at Pennsylvania State Correctional Institution Phoenix in Schwenksville, PA.
Cosby's representative, Andrew Wyatt, tells TMZ the comedian's day starts early with breakfast in his cell.
We're told from there, Cosby is escorted through Phoenix by a personal guide -- Bill's legally blind -- to use the prison's library, yard and other facilities. Dinner and lunch are either in his cell or an open room.
Since he's not in general pop yet, he spends a lot of his time chatting with prison staff. Wyatt tells us Cosby has mentioned many times how respectful the staff is and how well they've treated him.
Cosby also gets daily calls from his wife, Camille. We're told the calls are only for a few minutes, but convos almost solely revolve around the plan to appeal his conviction. It'll still be at least another week before Cosby can get visitors.
Meanwhile, as Bill Cosby settles into life behind bars, he will undergo a rigorous evaluation to determine the extent of his sex offender treatment ... and it all hinges on how much of a danger he poses.
Cosby will go through a programme called Responsible Living: A Sex Offender Treatment Programme ... something all sex offenders must complete as part of their sentence.
There are seven phases ...
-- Phase 1: Responsibility Taking
-- Phase 2: Behavioral Techniques
-- Phase 3: Emotional Well-Being
-- Phase 4: Victim Empathy
-- Phase 5: Anger Management
-- Phase 6: Sex Education
-- Phase 7: Relapse Prevention
According to the Pennsylvania Department of Corrections, Cosby will go through an evaluation process to determine what category of risk he falls in and what sort of treatment is deemed fit in the state sex offender programme.
If he falls into a moderate-high or a high-risk category, he'll have to complete all seven phases of the sex offender programme.
If he falls into a low or low-moderate risk category, he's just required to knock out Responsibility Taking, Sex Education and Relapse Prevention.
