Question about the Iphone 3G.

Well im thinking about getting the IPhone for christmass and I was wondering what is a data plan. The plan I want is $40/month but the data plan is $30/month so im wondering what does the data plan actually do that justifies $30/month?

i just got it and the data plamn for me is 30 dollars and its for unlimited internet access and what not, and the unlimited texting wouldve been like 20 bucks but then i set up and unlimited family texting plan for my parents which was a total of 30 dollars for all three of us, so it was liek ten dollars per person and the cool thing is, that the texting can go to any network and not have extra charges so its not just between the three of us and its not liek i would ever text my parents haha,

soits a total of 40 dollars a month for me
