Google has launched a new version of its online Google Translate tool optimized for the iPhone and iPod touch.

The new application is “optimized for speed, supports all of the existing Google Translate language pairs, and uses a client-side data-store on your iPhone to hang on to your past translations so you always have them at hand, even if you can’t use the local data network.”

Google Translate for iPhone and iPod touch is available at the link below.
