So ATT says I'm not eligible for an upgrade, yet I qualify for the "No commitment" price(even though I've had iphone 4 since launch day ). The price given is $449.99. But it says that is the "2-year term renewal" price. What is up with that? That sure sounds like a commitment to me. I'm confused. It seems like the language on ATT's website is awfully unclear. Can anyone here help clarify for me?
