Mates, I found the solution for this mod.
Thanks to Inebriate for pointing me in the right direction
Mates, to do this mod, we actually have to modify two templates for version 4.1.5:
1) /main/register_billing_address.tpl
2) /main/register_shipping_address.tpl
In both cases, simply locate the following respectively:
{if $default_fields.b_state.avail eq 'Y'} ...... {/if}
{if $default_fields.s_state.avail eq 'Y'} ...... {/if}
And place it after:
{if $default_fields.b_country.avail eq 'Y'} ..... {/if}
{if $default_fields.s_country.avail eq 'Y'} ..... {/if}
(again respectively).
Cheers!
