My wife just used her full upgrade to get an iphone 3GS a couple months ago. The thing about wives is that they always want something else though. She now wants a white iphone 4 when it comes out. When I go to our account and look at upgrading it only gives me the full price option. Based on at&ts site it sound like she should be eligible for an "early upgrade" price of $450. Do I have to call to get this price?
