Comment 3 for bug 303748

Mostly from here http://listing.driveragent.com/usb/0421 and other websites (cross-referencing the findings to make sure this is the real deal) and my own sources.

It should be noted that Nokia phones with the NNNN (where N is a number) model numbering scheme would also work as modems, but adding them should follow some testing, as most of them are S40, not S60 phones.
