How can I change the account used for contact sync? My phone currently synchronizes the contacts with my personal Google account. I would like to change that so it would synchronize the contacts with an other account of mine. I added the other account, but in the synchronization settings it's empty. I can't see the same options that I see in my personal account's settings. (My personal account contains Gmail, Google Calendar, and Contacts... there isn't Gmail and Calendar associated with my other account, so don't seeing it might be expected, but it definitely has Contacts.)

What can possibly cause this? Is there a way to still make the synchronization happen that way?

(I use Sony Ericsson Xperia X10 mini pro with Android 2.1, and I don't want to root my phone and load a custom ROM yet.)
I think Press Menu > Settings > Accounts and Sync > and Select the Account > then it should Display Options with checkBoxes like Calender, Contacts, Email...
Thats what I have got in my Phone Running Froyo Good Luck
