The Galaxy S6 is going to be a big deal for Samsung after the lackluster performance of the Galaxy S5. Samsung itself has been posting teasers all over the place, but the images posted on AT&T and T-Mobile's sites could be the best look of the unannounced device yet.

The two images are identical, with the exception of the color scheme. It's just a profile shot, so it's hard to tell if this is supposed to be the rumored "edge" version of the device with the wrap-around screen. The lines of the GS6 are certainly reminiscent of the Note Edge, though. And that back, is it metal or plastic?

The "six appeal" (ha, get it?) image doesn't reveal much else. There's a physical home button visible, but of course there is—it's Samsung. For everything else, we'll have to wait until Unpacked.
