Customers bringing in a working iPhone 4 will receive at least a $100 Best Buy gift card good toward the purchase of an iPhone 5 with a two-year agreement. Those bringing in an iPhone 4S will see their trade-in worth at least $200 toward the purchase of an iPhone 5.
The trade-in program isn't valid with T-Mobile and no-contract iPhone models, and trade-in value may vary depending on the condition of a device. The deal requires the activation of a new two-year contract with Verizon, AT&T or Sprint, and customers must be upgrade-eligible with their current providers.
Devices with cracked screens or water damage aren't eligible for the program, though Best Buy says on the program page that stores "would be happy to recycle" phones for free.
The deal runs from Thursday through Sunday, August 18. It is available only to in-store customers.
Best Buy has been running its trade-in program in limited bursts for some time now. The most recent occurrences were in May and then in June of this year. The retailer also recently offered trade-in cash for iPads.
For those looking to trade in their iPhone, iPad or MacBook toward an item other than an iPhone 5, or perhaps seeking cash to save toward Apple's anticipated "iPhone 5S," the AppleInsider Trade-In Guide is also available with special offers from leading trade-in partners such as Gazelle (pays cash), Amazon (Amazon Gift Cards), andNextWorth (cash).
