I was under the impression that its just the chip that operates the little usb port on the side of the unit has been changed, so it now no longer supports usb networking... I pretty sure the ext port has the same function (i.e. the BoB just breaks out the usb connector from the ext port), and usb devices work off the bob (of course).
Anyway, welcome to the community. I look forward to seeing your developments... of course, as a F100 owner I would love you to work on this (a dpad mod would be good!), but if you are planning on buying new, only F200s are made now. Still, as both units are almost identical, I hope anything you work on can be easily cross compatible!
oh, and check out: http://wiki.gp2x.org/wiki/Main_Page if you haven't already
