A new iPhone is expensive, which is why Apple’s trade-in program is so popular. Take your old phone in, and you’re immediately credited towards the purchase of a new iPhone. When it works, it’s sublime. Recently launched in China, Apple’s iPhone trade-in scheme isn’t going so well, it seems. According to a new report, Chinese customers are nonplussed about the offers they’re receiving from Apple, and say they’ve been able to source better deals elsewhere. Apple officially launched the trade-in program to all 18 Apple Stores in China yesterday.
