One of the longest UA I've seen.

YahooSeeker/M1A1-R2D2 is a Mobile Web crawling robot. The YahooSeeker/M1A1-R2D2 crawler collects documents from the Mobile Web to build a searchable index for searching on handheld devices like mobile phones, PDA's, and others.

Yahoo picked a particularly-long mobile phone UA to spoof there!

How about this badly-broken User-agent string from Google's mobile search robot, just seen today:

From 66.249.72.16 (crawl-66-249-72-16.googlebot.com) :

"\"Nokia6820/2.0 (4.83) Profile/MIDP-1.0 Configuration/CLDC-1.0 (compatible; Googlebot-Mobile/2.1; +http://www.google.com/bot.html)\""

Somebody got "escaped-quote" happy over there... :)

As of its most recent visit 30 minutes ago, the Googlebot-Mobile User-agent string appears to have been been corrected some time in the past six hours. :)
