Brilliant news that Orange seem to be on the case. Thanks to anyone who helped things along and even if you weren't directly involved, thanks to Connor for the info.
Spider, I don't know how to get qr codes up bit if my experience is anything to go by it's a case of them showing up in searches or not. I guess you're best off talking to T-mobile since it seems to be resolveable by networks.
Edit: btw, thanks for checking for Robo Defense, got it installed now :-)
