Gmail’s contact manger started to include information from Google Profiles. You can also find your Google+ circles in the sidebar, below the list of groups.
By default, the data obtained from Google Profiles is displayed below the information you’ve entered, but you can combine them: go to a contact page, click the “More” dropdown and select “[Show external data] inline”.
It’s interesting to notice that the Google Profiles data is automatically added when you enter an email address associated with a profile. To remove this information, just delete the corresponding email address.
The latest features are also available at google.com/contacts, which has recently switched to the new Google Contacts interface, but you can find them in the old Gmail interface, as well.
