Owners of the Sprint Palm Pre and Palm Pixi have a nice firmward update awaiting them. Palm published the news today, announcing the sole but virtuous purpose of the update is to fix a Microsoft Exchange bug that has been causing turmoil for calendar users.
More specifically:
This release fixes an issue in which the Calendar app displayed no events for any account after a user synchronized Calendar with an Exchange account. With this update, Calendar events now appear correctly after an Exchange sync.
