This. Pretty much anyone who called the retentions department (877-775-4886) and complained ended up getting their 12 month upgrade back, even people who switched to Sprint for the EVO 4G and even people who switched a few months later for the Epic or other phones. Pretty much anyone that qualified for Premier status before the policy change. There's also the people on plans with unlimited minutes, who got switched over to Premier Gold and never lost their 12 month upgrade benefits.
Hell, there's still two or three other ways to get a 12 month upgrade outside of that... You can bump your plan up for three months to qualify for Gold then change it back at no charge (net cost, $20x3 for those months). You can buy out your contract, which basically means paying the ETF, but after a year it's only like $100 which all-in is cheaper than paying full price on contract ($200 + $100 vs $450+). Some people have even managed to upgrade their Airave "line" (it's not, but that's how Sprint's system is set up) at Best Buy or Radio Shack to get a new phone (Sprint's system won't let you directly but I guess it does thru 3rd parties, and you're still renewing A contract with them anyway). Hell some people even did that for Airave's that they got and use for free when they complained about their signal at home thru the same retentions department I mentioned before.
Some of that is a little sketchy, most are just loopholes... At the end of the day Sprint cares more about retaining paying customers right now then eating it a little on some early upgrades. That may change if they start to grow after the AT&T/T-Mo debacle and the competition's tiered data pricing, but that's where we stand today.
Plenty of ways to get 12 month upgrades out of Sprint even if officially they took it away from most plans. Hell, if nothing else Sprint still lets you renew early (12 months) in exchange for a $75 discount; so at worst a current EVO 4G owner would pay $375 ($450-$75), and they can currently trade in their EVO 4G right at a Sprint store for a $150 credit (even tho it's $100 new on-contract!), so that's $250 all in (or they can Ebay it for $50-$100 more). That's all completely official and will still be true this time next year. Zero reason for anyone to pay full price, zero.
It amazes me how uninformed the average consumer can be about his choices, people miss out on so many things over sheer ignorance. Ya gotta know how to play the game...
