First announced at CES, the Earth-friendly Samsung Galaxy Exhilarate goes on sale June 10 for about $50.

The Samsung Galaxy Exhilarate is eco-conscious.

AT&T typically isn't the carrier you think of to promote its handsets in an eco-light, but that's about to change with the Samsung Galaxy Exhilarate, a 4G LTE Android 2.3 smartphone we first saw at CES.

The $49.99 phone (with a new two-year contract) has components made from 80 percent post-consumer waste material and comes with a more efficient charger, AT&T says. It will go on sale June 10.

In addition to 4G LTE, the affordable phone features a 4-inch Super AMOLED screen, a dual-core 1.2GHz Qualcomm Scorpion processor (based on ARM Cortex-A8 architecture), a 5-megapixel rear-facing camera with 720pHD video capture, and a 1.3-megapixel lens up front.

AT&T and Samsung will also add their own apps, including AT&T's subscription-based U-verse Live TV.

The Exhilarate is the first of a string of phones that AT&T plans to certify in its new eco-rating system launching this summer.
