New Social Icons Please

I love this theme but could you please update the social buttons which display in the header so that they are high res (retina ready)? They also need to be changed to use the current logos of the social networks they are representing. E.g. Twitter haven't used the 't' logo in ages? Should be the little bird. If as a developer you're looking for good icon sets for the social networks, maybe consider http://www.flaticon.com. Thanks.
