What are the prices of iPhone 4 at at&t?

Hi, I've been wondering at the at&t store iPhones are 99 cents. My friend said she got a iPhone 4 at at&t and she said it's 99 cents and she said for the payments are like 50$ a month, She also said it doesn't consider any contracts or nothing. Is this true?

Well, the iPhone 4 is $0.99 if you get a 2-year contract, and the lowest plan will run you about $60 because any smartphone requires a data plan mandatory, for $60 you will be getting the Nation 450 plan (lowest plan possible $40), which gives you 450 mins for land lines and other providers, 5000 mins for nights and weekends and unlimited mins to any at&t cell phone.
and you will be getting the lowest data plan which is 300 MB ($20)

so the total is $40+$20=$60 monthly
