Tip: In most cases, the early termination fee is applied for each phone in your account, not just for the account itself. I went into Cingular to cancel my account and move to Verizon (just because I am disgusted with Cingular's service). I was told by the representative that it was going to be $175. Well, now my bill says $525 and a call to the customer service department confirmed that it was in fact $175 per phone and not $175 for the entire account.
Bastards.
