Funnily enough, I was messing around with my iPhone today and discovered that Google had opened up a Google Translate version, specifically for Mobile Safari. Now this is not a native app, but a handy way of getting quick translations on the go. It’s available at the same address you access it on your computer - www.google.com/translate.

This goes with the other list of web apps Google have developed or the iPhone, such as Reader and GMail (although I just use Mobile Mail).
