Old Phone Is Worth Something
If you are excited about the new iPhone, and always need to have the latest and greatest, you’ll be pleased to know that Apple is now allowing you to trade in your old model. They’ll give you credit for functioning older models at Apple Stores.
And of course, the credit can quickly be used toward the purchase of a new iPhone.
**FYI: It didn't say how much older phones would be worth. But other brokers such as Gazelle.com offer anywhere from $10 for a working iPhone 3G to $350 for an iPhone 5 that is in pristine condition.
