Exception
When AT&T makes a change to your contract, say for instance - they bump the cost of Text Messaging up $0.05 for overages - there is a caveat in your contract that allows you to cancel your service without an early termination fee.
Sooooo.... if your looking to get out of contract, do it when AT&T makes it free for you, like when they changed their Cellular Data plans from unlimited to restricted, you could have canceled for $FREE.99
just an FYI
