I have switched over to the new version (previously beta) which automatically works out what country you are in.
If you have any suggestions please let me know
I have written a much newer version of unlock it which will work out where you are and by default pick the country you are in (hopefully) so you don’t have to scroll as much.
Its linked in the app after you go past the first page. Give it a try and let me know if it gets it right.
