Prestashop add Facebook & Google Connect

Hi I have a prestashop (1.4.5) shop, and would like to add "sign in with facebook" and "sign in with google" functionality. What I request: The ability for a user to sign in with facebook or google. I will provide an image to use as the buttons. When the user clicks on one of the buttons, a pop up appears and they are brought to the facebook / google page. When they confirm they want to give access, this closes and the user is then logged in (presumably by refreshing the page) When a user signs in, an account is created for them. This must include First Name, Last Name, Sex and Email. It must also set a dummy address with just country filled in (this is to ensure One Page Checkout) works I want to be able to place this button in a few places (by the log in button, on the registration page etc), so i need some code that when entered displays the button When a user is signed in, the button is hidden (of course!) Our store has a .com and .fr - the user must be able to log in when on either site (.fr or .com). This probably means creating 2 apps in facebook, and determining which one to call depending on language: if($language->iso_code == 'fr'){        $appID = "1111111111111111111111";        } else {        $appID = "2222222222222222222222";        } I would like to be able to tell i a user was created using the French or English - so maybe setting their country as UK if english or France if french - if this isnt possible then thats ok. The facebook app should only request basic info.
