My DD (7) is just at 48 inches tall, maybe a little under and I was very surprised that not once during our week long trip did they measure her. I was expecting it at both the Mummy, which she could nto wait to ride, and FJ and neither placed batted an eye when we went in. Now, she did have on some thick sandals that she loved but that might have only given her a half inch.
I have an IPhone and it never picked up any networks while we were in the parks, only the ones at the hotel for wifi connections.
I'm posting right now from in front of the Hogsmead Tavern on my iPhone over the 3G network. Works great and I have five bars for me voice signal.
