In this case the front page is default.php in the root.

I have already modified the file in unveiled.info and have just added a zero to the numbers to align the blog numbers.
Line 134 becomes Line 138

134. if( $l_Blog->ID < 10 ){
135.   printf( T_('Blog #0%d'), $l_Blog->ID );
136.   }
137. else
138.   printf( T_('Blog #%d'), $l_Blog->ID );

The code was
Line 134 printf( T_('Blog #%d'), $l_Blog->ID );
