I know this topic has been up before. I searched and searched but didn't find it. So, I am starting a new one and hopefully some of you won't mind answering again. I am looking to get a PDA (cellphone, I think this can be done) that is capable of holding the carb info from Calorie King on it. I think it would be so much easier than always carrying the book because we never have it with us when we need it! Can you please tell me what type of PDA you have and what you download off of Calorie King? Thanks.
