Updated to 2.3.4 3 weeks ago and just notice all contacts since then on android do not sync. Tried off & on with auto sync and background, and power save, restart. If i create contact in gmail it syncs and then if i delete it on Android it doesn't delet on gmail and any new contacts on andriod do not sync. Originally i had save new contacts to gmail yet is ti possible that after update it reverted back and if so how do i change that? or any other ideas?
