I was told which AT&T has altered the use agreement conditions for iphone users. ie., if any one terminates their 2-year stipulate early, they have to compensate an early stop price of $175 PLUS the superfluous the price of the device. So if the price of the iphone is $499 though the user got it for $49.99 w/ a 2-year agreement and he cancels prior to 2 years afterwards his cancelation price would be $175+$450 ($499 – $49.99). Is this true? How can I determine it? Can someone greatfully help?
