Any help would be good

Those are classes from OmniNetworking, which is a separate framework from OmniFoundation… the "missing required architecture arm in file" message probably indicates that the OmniNetworking (and OmniBase) frameworks you installed were compiled for desktop use, not iPhone use (the iPhone uses an ARM processor).
