We’ve already read about NextWorth’s great iPhone 3G trade-in deal, now we are hearing from Gazelle. They are another ‘Cash for Old Electronics’ company, one that has gone out of their way to position themselves as a ‘green’ alternative. For the next could of days they are offering a 10% bonus for trading in your iPhone (and not just a 3G either!). The cash paid specifically for the iPhone 3G seems a bit lower than NextWorth, but since they will also take your original iPhone at a 10% bonus it is worth a look.

Here is a snip from their press release:

Have an iPhone now? If you sell it to help purchase the new 3G S, start at gazelle.com/iphone to receive a 10% bonus on your trade in through this Friday.

If you don’t have an iPhone already but you’re thinking of selling other items to get cash to upgrade, visit www.gazelle.com/iphone-upgrade

They are also doing some other fun & good stuff:

Just for fun we’re running a contest on Twitter: Gazelle your old phone and put it to rest in peace by eulogizing it using #RiPhone on Twitter. Our favorite will win $199 this Friday. One of our favorites so far: “The time has come to lay to rest my newest cellphone that was the best. Now my 3g is old news the 3gs has got me singing the blues #RIPhone”

Gazelle for Good, our new fundraising service that helps you to raise money for a good cause by collecting used gadgets instead of cash, is taking off. This month more than 100 NPOs and individual fundraisers started a gadget drive. Visit gazelleforgood.com to start your own.
