long time coming (isn't it always with Sony Ericsson and AT&T?), but the January-announced W760 Walkman slider is finally hitting the US on contract. Announced today, the shakeable W760a will be available in AT&T locations, bringing with it 3G support, a 3.2-megapixel camera, AT&T Navigator and "full HTML web browsing." In case you haven't seen already, it'll be available in red, black and silver motifs, with the latter hue being exclusive to RadioShack for a limited time. Check it as early as today for $129.99 (with a 2-year agreement) after mail-in rebate.
