I'm re-reading and listening also...

and now I am getting more confused. In KC's interview where she discusses the cell phones, she said she got them both through Universal. If she had the Nokia first, with the nanny's number in it, then got the Black Jack, and only had a few numbers in it (the nanny's, JH, etc...), but the detectives have both sim cards, if the BJ is only a couple of months old, wouldn't the nanny's number be in the old sim card also, because Caylee had been missing a month, and if she dropped her off on June 15th, and had repeatedly called the nanny to find out where they were, then what number was she supposedly calling. If GA said KC left with Caylee on June 15th, then according to KC she would have already lost the Black Jack phone. Oh my goodness I am rambling...too much info. Have I got KC's timeline confused or is her theory just really not possible of having two phones and not having the nanny's numbers on both phones?
