By legal standards, I'm pretty sure that once either party violates their end of the contract, the contract itself becomes void. So essentially, if they don't hold up their end of the contract, you're not obligated to remain a customer for the rest of your contractual term.
So I suppose there'd be grounds for a massive class action suit against AT&T if they do change things, and then try to force customers to pay fees to break contract when they decide to get a real cellular provider.
