Palm released its sixth revision to webOS today. webOS 1.2.1 resolves some problems with Exchange that were introduced in 1.2.0. A few other issues were resolved including an issue with trying to watch or listen to streaming video or music as well as several security fixes including an issue found by webkit developers.
Oh, one more thing…iTunes syncing has been fixed and enhanced. Syncing of photo albums while maintaining the album structure now works. The full size original photos are no longer required to be synced back to the device.
A full list of changes and more on the update can be found at PreCentral.
