if you haven't been following, the Nokia pulse does not work either for push, so clearly it has to do with Nokia server as only two available push enabled services don't work which is distributed by two completely different companies, would be quite a coincidence if it has to do with apps itself. and as i think xms has one push server where its pushing all its messages to different devices from it and if its working fine on iphone abducting android then makes me think its not the xms at fault.
