I would hope they have the most Iphone users.....If they couldn't handle the heat then they shouldn't make it exclusive.
They were the only ones smart enough to agree to Apples outrageous terms. They had to get an exclusive. Really they were pretty smart about the whole thing. It seems like Verizon would have handled it better, but who knows. Doing CDMA would have made it harder to sell the phone around the world; they would have needed another version.
