Hi I'm currently trying to work out what my iPhone is talking to. It's making some requests to http://pds-init.ess.apple.com/WebObjects/PdsInit.woa/wa/getBag?ix=3 which seems to be a XML file, with some PEM encoded bits. I've included this below. I suspect that this might be APNS, but I'm not sure. Does anyone know what this is used for please ? many thanks
