There was a nice little present included in the BlackBerry PlayBook Native SDK 2.0 Beta update today. RIM also started rolling out a new version of the BlackBerry PlayBook 2.0 OS Beta (developer preview) that they first released at DevCon. BarracudaBob pointed out that once you register for the beta you will get a notification to download OS v188.8.131.5269 which is an update from the previous v184.108.40.20694.
Hopefully this update fixes the bridge issues with the previous update. This OS is intended for developers and not for end users but it sucks as a developer to have to cripple your device to use it for testing.
Hit that update button or register your PIN for the Developer Beta OS and let us know what you find!
