GoogleBot Wireless – Google Mobile Transcoding
It looks like we have a new GoogleBot that we need to worry about. The Google spider has the User Agent; “Nokia6820/2.0 (4.83) Profile/MIDP-1.0 Configuration/CLDC-1.0 (compatible; Googlebot-Mobile/2.1; +http://www.google.com/bot.html)” and comes from a Google IP address.
The bot is not incredibly new, but it is picking up speed. Many Webmasters are noticing this new creature explore their sites. There is a whole section on the Google Remove URL page under the Remove transcoded pages anchor.
