Yahoo seems to have a serertate bot for just about everything.
The following are very OLD:

User-Agent: Yahoo-MMCrawler
User-Agent: YahooSeeker
User-agent: Yahoo! Mindset
User-agent: Yahoo-Blogs
User-agent: Yahoo-MMAudVid
User-agent: YahooFeedSeeker
User-agent: YahooSeeker-Testing
User-agent: YahooSeeker/CafeKelsa-dev
User-agent: YahooVideoSearch
User-agent: YahooYSMcm
User-agent: Yahoo! DE Slurp
User-agent: Yahoo! Slurp China

During 2008 & 2009 Yahoo had an affiliation with Black Berry and Novorra

Yahoo LVLT-YHOO-8-12-144 (NET-8-12-144-0-1) -

"Mozilla/5.0 (X11; U; Linux i686; en-US; rv: Gecko/20060909 Firefox/ Novarra-Vision/7.3"

and also as a different UA:
KWC/1004 UP.Browser

I'm sure this is all changed in three years, given the ever expanding technology of mobile.

@wilderness, thanks for the info, but it didn't really answer my question...

I'm trying to identify Bing and Yahoo mobile bots so that I can serve up my mobile site to them.

"user agents" +mobile [google.com]

The second link provides an explantion of using "profile headers" to identify mobile requests, unfortuately, the same page does not provide an example of utilizing headers within htaccess. They may in subsequent pages.

Going through the SERPS you may even locate a website that offers a complied list of various UA's.
I don't recall ever seeing one in this forum.
