For most iPhone owners, trading up to the 5C is ‘free’

It’s called the Apple Recycle Program, and as I understand the deal, it works like this:

• You walk into an Apple store with your current iPhone.
• A staffer checks it out and quotes a price.
• If you are agreeable, the old phone gets wiped clean on the spot and you take home the new iPhone of your choice.
• If the old phone is worth more than the subsidized price of the new phone (i.e. After you sign a new two-year contract) you get store credit for the balance.
• Apple refurbishes the old phone, installs the most current version of IOS it can comfortably handle, and ships it off for resale in a country currently underserved by Apple’s higher-priced models. In India, for example, nearly everybody buys their mobile phones pre-paid (i.e., without subsidies).

We don’t yet know how many iPhones Apple will acquire this way or what it will charge for them. But we may get to watch the devices pour in on the supply side if, as expected, a million or more customers show up next week ready to trade in their old iPhones for one of this year’s new models.

My wife may be one those customers, having pre-ordered an iPhone 5C to replace her off-contract iPhone 4.

Figuring that the three-year-old iPhone 4 and the two-year-old 4S represent the sweet spot of this year’s trade-in market, I did some comparison shopping to build the chart above.

As you can see, my wife can get a better price elsewhere, but for convenience sake she’ll probably take Apple’s trade-in deal.

She’ll get a ‘free’ iPhone 5C, nearly $36 in store credit, and a new two-year contract with AT&T (T) that will set us back a couple thousand dollars before we’re done.

It would be fun to know on what shore the old iPhone washes up, but the Find My iPhone app doesn’t work on a phone that’s been wiped clean.
