Google released Google Translate for iPhone. Google Translate not only allows you to translate individual words across 24 different languages, but it plus allows you to translate arbitrary phrases.

Google Translate for the iPhone has been specially optimized for speed so you don’t have to wait a enlarged date on uncertain wireless connectivity in front of the waiter who speaks nothing else but German. In addition to the speed Google Translate plus supports all existing language pairs that are supported on the web based version of the translator, and uses a client-side documents store to store past translations on your iPhone. that enables you to have the previous words and phrases on your device to access them

inside a Metro tunnel with limited connectivity to the outside world.

The web app is cleanly laid out, with selector menus for the source and target languages, a field for entering your phrase, and an arrow that lets you toggle which direction the translation goes. Best of all, the Google Translate web app stores your recent queries, so you can load it up with a few handy phrases and not nag about erasing the earlier ones when you add more.

You can try Google Translate for iPhone, by point your iPhone web browser to translate.google.com.
