If you get the urge (or need) to translate while out and about, Google has just put the finishing touches on their Google Translate site, specifically targeted to iPhone and iPod touch users. All you have to do is visit translate.google.com on your mobile Safari browser and let the translating commence.
Google Translate has been optimized for speed and will automatically update language support as the regular version of the app is updated. If you are looking for something free and easy to use for simple translations, this is probably the way to go.
