I called a year ago to cancel 1 year into my contract, and they gave me a new phone at subsidized price. It all depends how adamant you are about leaving. Honestly, I'm 13 months in now, and going to call them again and just matter of factly tell them I'm going to a WP8 phone, and my two options are them selling me a 920 at subsidized price for another two years, or I'll just pay the $215 ETF and leave for a cheaper and unlimited plan with TMO, who is also currently giving $50 for switching (further offsetting the ETF). The reality is I hold AT&T service offer at a lower value, and they need to do more for my business. Since its not a bluff on my part, there's really nothing for me to lose. I've actually already sold my GS2, so I'm committed.
