Customers planning on swapping out last year’s iPhone 4S for the next iPhone can now do so on Apple’s website, using the company’s Reuse and Recycle Program. Using a third-party solution provided by PowerON, Apple’s site offers a quote based on the model and condition of the iPhone, then determines the actual value of the phone after receiving it. Customers receive an Apple gift card with the trade-in balance. Currently, the iPhone 4S in excellent condition has an estimated value of $345 for a 64GB model, while a 32GB 4S is valued at $330, and a 16GB 4S gets a maximum price of $285. Notably, third-party vendor Gazelle is also offering iPhone trade-ins with a guaranteed offer to lock in a price until Oct. 1. The company is currently offering $333 for a AT&T 64GB iPhone 4S in “flawless” condition, paying cash rather than store credit; the same iPhone 4S model on Sprint or Verizon will fetch $330.
