No, you are not allowed to bring digi cams in prison.
You are not allowed to mod games on the PS3. If you play online they will be allowed to take action against you because you violated the agreement that you made joining the Playstation Network.
If you PS3 has an internet connection the only place that games are allowed to be downloaded from is the Playstation Store

Yes. You are encouraged to write.
