Update my wife's Pre to 1.2.0 on the 29th. Today (2nd) she checked her calendar for the first time since the update and all of her data was gone! Contacts are there. I spent 2 hours on the phone with Sprint Pre specialists then Palm. There were no Level 3 people left...it was late...so for now I guess she's screwed. The real problem is that she didn't notice it as soon as the update happened so she's had two days of auto-backup that clearly was backed up with no calendar data...and that overwrote that last "good" backup from the day of the 29th. Had we seen it then, we could have killed it and let the cloud send it back.
