Today, found out that Synergy is not completely reliable as a backup for your contacts or calendar information.

I was instructed by a Palm support team member to do a partial erase. After the phone had been reset and I had signed into my palm profile and synchronized my palm profile I found that many of my contacts were missing. Fortunately it was limited to the contacts that I had manually entered in the phone after buying it but, nevertheless, it seems that those phone numbers etc are lost. The Palm representative recommended that I use Google as my default account on both contacts and calendar to prevent future data loss. I wish I had been told that when I got the phone.
