Utah County Inmates

What can i write about to some one in jail?

My boyfriend was taken to Davis County Jail here in utah for breaking his probation. i know nothing about this type of stuff! i finally found out how to send him a letter and got his inmate id#. are there restrictions to what i can write? restrictions on pictures(im not sending dirty ones obviously)? how long does it take for him to get letters generally? do they let them write back? he has to do 4 mo and its horrible! ah! he should not have messed up! can any one give me a run down how any of this stuff works? any kinda of messages would be much appreciated! i know he is not perfect, but no one is! he didnt kill any one or anything crazy like that! just stupid stuff!
how do i check with his po? i dont even know who his po is! his sister and his friend kinda keep me updated, but i hate asking for info cause they dont really know me and i dont really knwo them. its just akward.

Call the Davis county jail and ask how to write an inmate.
