Hi - noobie here just had my unit for 24 hours! Having spent a couple of hours tidying up all My Contacts in readiness to sync with my Hero I was a bit hacked off to find 500+ contacts based upon all my email via Gmail. So thought it would useful to share how to set up the Hero to only sync My Contacts, by default it set to sync All Contacts. I actually found this on a Google support forum at: Just want to sync 'My Contacts' on Android, not everything! - Google Mobile Help This is how to do it from there: Via People, open Groups tab and press Menu you have the option "Sync Groups". Press that and you have me the options: - Sync all contacts - My Contacts Untick 'Sync all', hit Save and you are done! Hope this helps.
