В целях оптимизации мобильного трафика, Nokia в браузерах Xpress перенаправляет трафик на собственные прокси сервера. Перенаправляется в том числе и HTTPS трафик. Прокси сервер устанавливает обычное HTTPS соединение с web сервисом, получая данные клиента в открытом виде. Затем оптимизирует их и уже через свое шифрованное соединение с клиентом отправляет пользователю. То есть на серверах Nokia наши приватные данные (пароли к клиент банку, номера кредиток и т.п.) присутствуют в открытом виде. Классический Man In The Middle.
