Similar to its web based translation service, the Google Translation Widget
for S60 devices translates a portion of text to another language. This widget auto detects the source language and you only need to select the language in which it will be translated to, enter the section of text and click the go button.
The unique feature of the widget is its ability to automatically detect the source language, which especially useful if you don't recognize the language and also, automated translations are quicker and easier.
Unfortunately, there are some limitations and missing functions such as support for site translations, dictionary and tools but you can always switch to S60 browser and use the regular web based translation engine as it works just fine and is maybe even better solution in some cases.
Google Translate is a beta service provided by Google Inc. to translate a section of text, or a webpage, into another language, with limits to the number of paragraphs, or range of technical terms, translated.
Unlike other translation services such as Babel Fish, AOL, and Yahoo which use SYSTRAN, Google uses its own translation software.
Google Translate, like other automatic translation tools, has its limitations. While it can help the reader to understand the general content of a foreign language text, it does not always deliver accurate translations. Some languages produce better results than others.
