Here's what I transcribed re: ER/Dr. Phil about the phone...
Dr. Phil:
He was texting. So right up till 9:30 hes texting and then just zip zero So he could have gone to sleep, right?
ER:
9:30 seems a little early for Dylan, but ummm
Dr. Phil:
Okay, what time would he usually go to sleep?
ER:
Probably about 11, midnight, somewhere around there
Dr. Phil:
So 9:30 would be early.
ER:
9:30 would be early, and its definitely early for him to stop texting, especially when he was so excited to see his friends.
Dr. Phil:
His friends on that end?
ER:
Yes, his friends in the southwest.
Dr. Phil:
And was he texting them up until 9:30?
ER:
I believe the last text was about 9:30 somewhere around there.
Dr. Phil:
To those friends?
ER:
Yes.
Dr. Phil:
Okay, so he was in connection with them until 9:30. Not another text was ever sent from his phone?
ER:
Right.
BBM - so the last text that night was from his cell and not an iPod. IMO
