I've been looking at the logs on my web site in my signature. Many of the browsers reported are of the form:

BlackBerry8700/4.1.0 Profile/MIDP-2.0 Configuration/CLDC-1.1 VendorID/123

I guess the vendor ID is one per operator, right? How can I tell which is which?

For the curious that were ranked as follows...

1 MSIE
2 Firefox
3 BlackBerry8700
4 Netscape (compatible)
5 BlackBerry8703e
6 Netscape
7 Safari
8 BlackBerry7130e
9 BlackBerry8100
10 Camino
