I want to thank you for posting about cellphones in the hospital since it prompted me to ask about this rule at the nurses station. The entire hospital (except the lobby - maybe other places I don't know) has little framed signs that say "No Cellphone Use" - So I asked about it.
The nurses and others at the station discussed it with me at length and it was informative. They said the hospital decided the signs were to encourage not to use cell phone (they won't kick you out if you do) but to discourage folks from walking the halls and talking (loudly), or even a group of family/friends standing outside of rooms talking loudly/laughing/arguing whatever... and it disturbs other patients in other rooms are very sick, resting or speaking with doctors, maybe at end of life ...and disrupts nurses, assistants, doctors who need to communicate to patients in a quiet room where the patient is focused. They said (in past experience) some people don't know how to be proper and respectful while on the phone and will have long conversations about anything other than the patient. They said that patients often get confused as they don't retain or remember what someone tells them (dr./nurse) because their family/friend is on the phone while they are there. They gave an example of a large family that came to visit their grandmother and the grandkids, nephews/nieces were talking on the cellphones, playing games on their phones and just acting like they were at a park outside her room - which disturbed other patients.
So I get it. They told me they had no problem with me using my cellphone. I feel kinda dumb that I didn't think to ask about this. Mom's been in this hospital before and I didn't use my cellphone then!
I'm more than likely will just "like" posts more than comment because someone is always entering the room...and I hate typing on a phone. This post took me forever! 
BUT now I can watch SLC on my phone and at least "like" posts or make short comments! So thank you everyone for helping me out!
