Use existing contact for "Me" in Ice Cream Sandwich My Nexus S has just been updated to Ice Cream Sandwich, and I notice that in contacts there is a new space for "me". Is there a way to assign the existing ordinary contact  for me (a contact with my name and details that I sometimes use for sharing with people, and sync with Picasa Photos etc.) to this slot?

It seems related to this question, but that is about the similar HTC specific feature found on some phones.
After trying forever (the "me" profile was never synced and could not be merged), this worked for me:

Install the Google+ app.
Set it to sync contacts.
Open your contacts again; your contact will now be set as "my profile".
Seriously.
