Q: Do I need to assign a name to both my iphones? I just got an iPhone 5, BUT I still use my iPhone 3GS as a camera

Do I need assign a name to both my iphones? I just got an iPhone 5, BUT I still use my iPhone 3GS as a camera & iPod, and will need to back it up and sync it occassionally, I have NOT named either phone yet, they are recognized only as "owner's iphone".

NOTE: I HAVE A P.C.

Is there any danger of not naming them, and itunes confusing them, and gathering wrong backup info, etc.

ALSO....Does turning the volume all the way down silence all phone sounds? In other words before I sleep, do I need to click that little switch on the left side of the phone to achieve complete silence, if so, is there an INTERNAL way to do this so I don't have to push my finger in there through my otter box case to turn it off.?

I have AT&T on my iPhone 5, and I was wondering if there was a way to save my voicemails permanently somewhere, because they get erased by AT&T every 14 days.

ALSO.....How do I manage my 20,000 photos, in "my pictures" in my PC, shall I have one folder which has ALL of photos ALL OF THEM.........In sequence and then create dozens of other folders by event, catagory, etc. I get SO CONFUSED on what to do with my photos, what is THE BEST WAY to keep them organized.

Thank You Very Much,
