The application is meant to give you a quick translation and also help you expand your vocabulary by remembering which words you have learned already. The translations are stored on a server so there is no large database taking up precious BlackBerry memory. You can also share translations by emailing them to a friend from the application.
There is no OTA option yet but we are working on it. The application comes in separate Spanish/English and German/English versions that can be downloaded at the link below.
