If you're like me, you probably have a few old or broken cell phones lying around your house - maybe even a 1980s dinosaur like the one pictured here. 

I could never bring myself to throw them away, figuring they'd just wind up in a landfill or even incinerated. So they're sitting on a shelf or in a box somewhere.

Now, here's a chance to get those unwanted phones recycled, and make a little cash in the process. From Friday (6/10) through Sunday (6/12), everyone who brings two old cell phones to Mondawmin Mall will be given a $10 gift card.  You can go green and get some green in exchange.

The event is sponsored by General Growth Properties, owner of Mondawmin and other area malls, in partnership with Cathy Allen, a West Baltimore resident who dubs herself the "Green Ambassador."  Among her efforts to green the urban environment, she's campaigning to plant trees in every public elementary school in the city.

Remember, you need to turn in TWO old cell phones to get a gift card. The swap will be taking place at Center Court at Mondawmin, 2401 Liberty Heights Ave. from 1 p.m. to 8 p.m. Friday, from 10 a.m. to 6 p.m. Saturday, and from noon to 6 .m. Sunday.
