When you have the 'Social Profiles - JomSocial' plugin enabled, you can map the social profile data into the JomSocial profile fields by configuring the JFBConnect > Profiles area. However, there are only certain field types that we currently map into, such as text box, gender, url, date, birthdate. Is the location field a different type than those or is it just a text box? If it's a new type, I'll have to look into a code change to support it.
