Xperia X10 Mini/pro :: It Does Not Sync Contacts

After the update to 2.1 last year, i have not been able to sync my contacts with SE sync and Gmail contacts sync. Everytime i try syncing from the phone i get an error. I did not bother because i assumed that gmail automatically syncs. Over the weekend i used SEUS to repair the phone, after which, my contacts were automatically downloaded from gmail. This morning i tried calling one of my contacts and realised they are not on my phone. Manually checked my Gmail contacts and realised most of my contacts were missing. I deleted all contacts on gmail and requested a fresh sync. Everything except my contacts gets synced. The same is the case with SE sync. Has anyone noticed this? Is there a way to correct this?
