How to theme the PAGE template for user account? The user account page should have the title(name or username),user pic on the left, basic details like gender, city, state and country to the right. The local tasks tab should be available below those regions.

I tried page--user.tpl and page--user--profile.tpl. Doesn't work. 

Am using drupal 7 with an adaptive sub theme and don't know PHP much.
it can be override with user-profile.tpl.php file.


  Default theme implementation to present all user profile data.
  
  This template is used when viewing a registered member's profile page,
  e.g., example.com/user/123. 123 being the users ID.
