My university also uses Eduroam,
my user name is my student number + @hials.no

My iPhone connects without any configuration, tap enter password and usernname, connect, and accept license. rly straight. (also it should be noted that any network stack should be able to recieve the license which is sent over air on eduroam)

My Linux laptop, using a network manager called NetworkManager, i just select the network as any other, enter username and password, but one setting i have to change in a dropdrown menu.

On my macbook, i have to deselect a security setting deep within the network manager somewhere, i dont remember of the top of my head, but i used a pdf file i got on class fronter (software we use to hand in tasks if we have any and similar stuff) for an old OS X version, with a lot of redundant steps for the current Snow Leopard (and also Leopard).

On Windows 7 it was a nightmare, the XP/Vista pdf guide on fronter was only helpfull half ways, and after some tinkering, its up and running.

AFAIK Eduroam does not use Mac filtering in the manner as spoken about earlier in this thread (it may be different on some school idk), afaik they just ban certain mac addresses that they don't want.

It should work on N900 since it worked in linux generally, if not, with us there is a guest network which is far easier to hack, you might have one too (maybe hidden essid?) on our guest network the key is changed weekly or so. (i have yet to try since im waiting for my bloody phone in the mail)
