Hi George

I can't speak for any other plans or phones but DH and I have the iphones and I just checked our bill over at ATT.com to be sure. We have had the family plan forever (love it!) and the $30 data plan is per iphone unfortunately. DH and I both have iphones so we have two $30 charges on our bill but DD15 is only allowed to have a phone to text on (no data for her!) so she only costs me $9.99/mo - well, unless you count the fact that I did add the unlimited texted because of her!!! ATT loves us

but I have to say the love goes both ways. Now that we have our iphones, I don't know if we could ever go back to just old phones again. When I went to the store to chose between the iphone and the crackberry, the salesperson spent 15 min telling me the differences between 2 different crackberries but then said if he had to choose, he would still pick the iphone. Why? Because it is constantly updating with as many apps as you could possibly want! I'm a sucker, I was sold

Best of luck in your decision!
