I was all set to purchase a 6 for my wife and myself (not sure what I want yet---I'll just wander in on the 19th and fondle a 6 Plus first) and pay full price, but....
We are both grandfathered unlimited. We did renew and upgrade last year with the 5S. I assumed that we couldn't get a phone discounted and subsidized, but I was wrong.
Wife's 64 GB 6 was full price, minus $200 credit. I don't really want to read the fine print why, but $549 for the phone and we still get to get a 6S next year at the $299 price point...plus keep the data and calling plans we have now.
I looked into the Mobile Sharing plan, and $100 + $30 for two phones is slightly cheaper than what we have now for voice, data and texting....really wasn't worth the hassle of switching.
I get the same $200 credit on a 6 Plus, no matter what size, so $200 off the retail cost of the phone...I'll take it.
When the smoke is all clear, we will have two 64GB 5S to either keep or sell off. We will have 2 iPhone 6 models, both 64 GB. And a year from now, have the option to upgrade again...only at the full subsidized price if we choose to. And peddle this year's phones to offset the costs.
Maybe someone will come along and point out where I'm taking it up the rear on this, but meh.
Oh yeah, just finished ordering the wife's phone. It will come when it comes.
