Trading in your old iPhone can help you save some money on your new iPhone. But how much?{.intro}

Many retailers, including Apple, Best Buy, major carriers, and more, let you trade in your old, used iPhone to reduce the cost of your new iPhone. The exact amount you'll get for your trade-in, however, varies from place to place and from iPhone to iPhone.

In determining the values listed below, we checked off that the phone was in good working condition with minimal wear and tear and no liquid damage. The condition of your phone and, therefore, the trade-in value will vary depending on what you've put your phone through during its lifecycle.

What about my iPhone 3G or 3Gs?

Unless you've been holding onto an iPhone 3G or iPhone 3GS in its factory-sealed packaging, it's not worth much anymore. Hold on to it if you're the sentimental type or send it to Apple's recycling program so it can be disposed of in an eco-friendly manner.

Both AT&T and Sprint also offer free electronics recycling for your old iPhones, as well as a bunch of other old tech you might have sitting around the house collecting dust. Best practice would be to call ahead before lugging all your stuff down to see what they accept for sure or check their respective buyback/recycling lists.
