it wont render without css.
ibrowse may be able to show aw.net, amiga-news.de and aminet, but thats probably about it. sorry to say.
If you set your profile on amiga.org, eab.abime.net and others to use their respective mobile themes, you can use them on iBrowse. I've done it with EAB and nearly sure amiga.org worked that way too.
