I'm using my old Vodafone SIM in my unlocked MS2. I've switched on Read Receipts but receive diddly. Anyone any ideas why it's not working? p.s. There seem to be a few features that don't seem to work quite as they should on my handset. In-Pocket-Detection doesn't work at all. Changing the orioentation of the device doesn't reliably change the screen orientation (for the same apps), though sometimes a bit of a shake kicks it into life ... minor irritations, but maybe something to do with quality of manufature?
