"All Treo 680 users should install the Camera Update." That's the official directive booming down from the Palm heavens this week as the first software patch for the stubless, Palm OS-based smartphone has gone live. While there's nothing terribly interesting going on here, the update seems pretty critical nonetheless -- if you value battery life, that is. The shipping software apparently has a tendency to leave the cam enabled even when the device is in standby, leading to a rather staggering power draw. No new features, no interesting changes, just one rather important fix. We can almost hear those overtaxed 680 batteries breathing sighs of relief already.
