The leak apparently came by way of the last resort reset option for a Pre that is not working correctly, called the "webOS Doctor". When the customer ran the Palm utility that reloads the OS on the phone, surprise surprise, Palm webOS 1.2 was loaded!
Looks like some webOS 1.2 goodness is on it's way to us soon. Let's just hope that Palm has taken the time to address the numerous Bluetooth issues with hands free links in many popular vehicles.
Check out some screen shots over on PreCentral.net.
