In the market for a fancy flip? A mild update to an ancient smartphone, perhaps? Either way, Sprint's got you covered -- both the Samsung m510 and the Palm Treo 755p have gone live on the carrier's website. Despite the fact that the 755p's available in two snazzy colors, the m510 wins the fashion competition hands down in your choice of black or pink. As we mentioned earlier, get it for $129.99 on contract or rebates; the 755p will run ya another $150 at $279.99.
