already seen a couple of these semi-officially, but it seems that Samsung has now fully, honestly announced these four fresh models for all of the world to ogle. There's actually not a lot to see here -- they're so well-buried in Samsung's literature that we were only able to find the S6700 ourselves -- but they present interesting options for anyone looking to get in on mobile music at a ridiculously low price point. Starting at the bottom, the M2310 and M2510 together formulate a powerful one-two flip / slider punch (okay, that's saying a bit much) with dedicated music controls and support for up to 8GB of microSD storage; the M2310 has a VGA cam while the M2510 steps it up to 1.3 megapixels. Moving upwards, the C5510 adds in a dual-band 3G radio, 16GB expandability, and a 2 megapixel fixed-focus camera, while the S6700 slider (pictured) tops out the range with HSDPA, a 3 megapixel camera with autofocus and dual-LED flash, GPS, and 120MB of storage on board. Still no word on when or where these are launching, but it seems like the S6700 might be available in some regions if you look hard enough.
