Yesterday, after months of dealing with a half-broken iPhone, I went and bought a brand new 3G at my local AT&T store. So, I asked about upgrading to the iPhone 4, whenever it releases. One of the managers told me that since I just got a new phone, I won't be eligible for the discount price. Of course, I already knew this, but I was wondering how much it will cost to upgrade to the new one releasing this summer? Now, let's say the cheapest model will be $200. I'm guessing the price for me will be anywhere between $400 and $500?
