Photo Translato Just take a picture of text in any language using your BlackBerry camera and Photo Translator will instantly capture the text and translate it.
It is incredibly useful in situations when quick translation is needed: in airports, train or bus stations, restaurants and many other places
Navita is a free five language translator for your Blackberry. Its similar to bbtrans also made with a very simple interface. I don't know what translation engine they are using but it seems to be okay and fast enough. My officemate claims the German translation works well and is usable
