Trade in your old phone for a Best Buy gift card | Phone/Device Issues and Features | Consumer forum

I'm not sure if this is the right forum for this but Best Buy's running a promo where you can trade in your old cell phones for a Best Buy gift card or if the phone isn't worth anything (to them), they'll plant a tree in your name. Click here for more info.

In terms of the SO phone models, the Nokia 1112 and 1208 aren't worth anything (except a tree) but the 1661 is worth up to $6, 1680 $11, 2760 $13 but they don't list the 5130.

I realize it's not very much but it's better than nothing.
