My family is moving to an area where AT&T only has 'moderate' coverage. It looks like Verizon is the major carrier there, with 3G service everywhere. We really don't want to switch carriers, but if we have to, is there any kind of program Verizon offers for AT&T customers switching? We have an iPhone 4, two 3GSs, and a non-Apple phone. I calculated it would cost $819 to buy out of our contract, which is ridiculous. With Verizon's Trade-In program, they would give us a combined $360 for the phones, which would leave us with $459 to pay, still a lot. Is there any cheaper way to switch?
