I know there have been a lot of threads on this, but I've never managed to find a working solution. I have all my contacts in my googlemail account. When I go to settings/Accounts & Sync on my Desire, and sync, it seems to sync from the Desire to my googlemail page on my PC, but not the other way round - which is a problem for me because all the correct contacts are on my PC. It also tends to duplicate or even triplicate most of contacts. On the PC there is the merge setting, but not on the Desire. I've tried deleting all my contacts on the Desire, but syncing doesn't repopulate it. I have all my appointments on my Desire calendar, which seems to only sync from my PC to the Desire. As I enter my appointments on the Desire, and would like to have them on my PC, this, too, is a problem. Where am I going wrong?
