Like Slippery-Pete was saying, it DOES NOT take 2 years for AT&T to make back the extra money they paid to Apple for your phone. If you're paying a $100/month cell bill, within 6 months to 1 year they've made that money back plus much more. At 12 months, you've already given them $1200 + $199 or $299. I myself have given them $1500 for a phone plus service for the past year. I think they've made some profit
All you people who are sitting there and calculating out x dollars over 2 years and saying we haven't paid off our phones- that's YOUR OWN calculation, NOT AT&T's calculation. AT&T has made a profit, and everything is negotiable.
If I finished my contract, and continued to pay for 2 MORE years going month-to-month without a contract (which I have done with other phones), would AT&T then say "oh, you've already paid your subsidy for the next phone"? No, of course they wouldn't. The rate plan is the rate plan, regardless of the subsidy. The subsidy part is completely negotiable, and separate from the monthly rate plans.
