38-year-old Avtar Singh ended in jail because of the translation app on his iPhone.
He was part of a fake wedding scam involving "fiancees" from Eastern Europe. The idea was that Singh and others who weren't UK citizens, would marry women from the newer countries of the European Union, thereby securing their residency and permission to work in the UK.
As Metro reports, the registrar became even more suspicious when the bride, from the Czech Republic, turned up at the wedding in a dirty dress and appearing to be less than overjoyed at her nuptials.
Singh and another man who attempted to marry a Czech woman were jailed for a year for attempting to get around the UK's immigration laws.
