Since the resale value of the iPhone after 1 year exceeds the ETF for any of the major carriers, I was wondering if you could theoretically jump carriers every year, sell your old iPhone, and get a new one at the subsidized price, all for less than the edge/next scheme. For instance: If you buy a new 5s in September 2013 for $200 with VZW, a year later your ETF will be $230. If you port out to ATT In Sept 2014, and sell your 5s for $300, you would have $70 to put towards a new iPhone 6 from ATT. Assuming the price point is the same at $200 for a 2 yr contract, you could get the new iPhone for $130, $165 if you couldn't get the activation fee waved. And going back to VZW in 2015 would have similar results. This assumes that both carriers meet your needs and are the same from an operational and price for service standpoint. So, wouldn't $130-$165 per year be cheaper than the edge/next scheme, or have I missed something here?
