Looking to make some cash on that old iPhone 3GS collecting dust in your desk? Amazon is now accepting iDevices for its Electronics Trade-In program, currently in beta. Surprisingly, the prices being offered look good!

Launched earlier this year, Amazon’s program only recently began offering trade-ins on Apple products.

Among the sample product offerings are an iPhone 3GS 32GB with a trade-in value of $242 “like new.” In “good” condition, the same item goes for $185.

Want to sell an Verizon iPhone 4 32GB? Amazon is offering $398 for that model.

Amazon, which is actually using a third-party to run its trade-in business, offers free shipment for all items. Once Amazon receives your item, a gift card in the amount of your sale is deposited into your Amazon.com account.

All items must be in working order and arrive in good condition.
