A more buttoned-up color combo inbound for AT&T's Centro

We're used to carriers typically releasing conservative hues first and resorting to the more wild goods down the road in an effort to revive sales and reach new target demos, but for whatever reason, AT&T is taking quite the opposite approach with its Palm Centro. A gander at AT&T's business site for the low-cost smartphone reveals that "Obsidian Black" is the next stop on the Centro train following the initial launch in Glacier White, so if your job calls for green keypads to be kept to an absolute minimum, hang tight. Right now they're just listing it as "coming soon," but we can't imagine it's too far off.
