Yahoo Nokia Symbian crawler

Is this a Yahoo crawler for mobile aps?

Just a question. Is this Yahoo? Came on the site at 4 a m and left at 2 p m. Are they crawling for phone users? Does this go to the Yahoo search engine? Wasn't sure if it was the Yahoo crawler or someone using Yahoo to do a crawl anonymously. Are these types of crawls generally welcome by websites?

And now, from the Sweat Equity/DIY Department:) --

1.) Did you WHOIS the IP address? I show huge chunks (if not all) of 209.191. to be Yahoo.

2.) See the info link in the UA string for answers: [help.yahoo.com...]

FWIW: All of the hosts I've seen from similar .search.mud.yahoo.com Hosts* using the exact same UA requested/respected robots.txt. Yours, too?

*For example: 209.191.82.245 = mssn01.search.mud.yahoo.com

I just typed the whole string into Google and found a site that lists all Yahoo's user agents, and this one is there. It says: These user agent strings belong to Yahoo!’s mobile web index crawler. I don't have a mobile site and don't know what my site would look like on a mobile device. So, the bottom line is, if they want to crawl, that is fine. I guess they have been around for awhile, but I am just now seeing them crawl my site. I usually see Yahoo Slurp. By the way, the reverse DNS lookup is cr04.wap.search.mud.yahoo.com. Thanks Pfui.
