If I change a contact from my pre that was originally pulled from Gmail, the change shows up on Gmail. Contacts that the Sprint store transferred from my old phone will NOT sync to Gmail. All those contacts have the Palm Sync icon (2 curved arrows) when I go to edit that contact. I don't see a way to change that.
New contacts will sync with Gmail. I guess I'm going to have to manually transfer all my contacts to Gmail, delete contacts off my phone and resync with Gmail. It's going to be a long night.
I deleted my Google Account on the Pre and then added it again and now it syncs fine. New stuff input on Pre is visible on Gmail on PC after a Sync. I lost about 20 contacts that I had input on the Pre previously when I deleted the account since I couldn't sort by newest entries, but its better I do it now than continue to operate in that broken state, I'd lose more if I waited.
Here's what I figured out and worked great two ways sync
When you want to add new contact to your PRE, next to the name make sure you choice which profile you want to save the new contact to, if you choice Google, it will sync it to you Gmail account right away, but if you choice Palm Profile it will not sync it to your Gmail account.
Still searching to learn how can I sync my Pre profile to my Gmail
