Sprint will be introducing a “green” Android smartphone tomorrow, and it turns out to be that Droid Pro-like handset we’ve seen a few times in leaked photos. First tipped in promotional material for sales reps, the Samsung Replenish SPH-m580 is a Froyo-powered portrait QWERTY candybar featuring a 600MHz CPU, QVGA display of unknown size, and two-megapixel fixed-focus camera. Perhaps its most interesting feature — which is not pictured above — is an optional solar panel cover which presumably powers the phone via sunlight.

Sprint CEO Dan Hesse is expected to announce the rest of the details tomorrow afternoon, although thanks to a publicly-available website, we learned that Replenish will launch on May 5th — and probably for not much money.

Update: Apparently Replenish will also come in blue and raspberry pink along with black, and is made at least somewhat from recycled plastics, according to PhoneScoop. Oh, and the screen size? 2.8 inches.
