Tried MS support about an hour ago, they were spectacularly unhelpful.
Here is the transcript;
"Please wait for an agent to respond. You are currently '1' in the queue.
Privacy Statement
You are now chatting with 'Elka'.
Elka: Welcome to Microsoft Customer Service Chat, Dave.
Elka: Please give me a moment while I review your question. Would that be alright?
Dave Brotheridge: sure, thanks
Elka: Thank you.
Elka: For assistance on this though, I recommend using this link below:
Elka: click here for Windows phone support
Elka: That's where you can find support information for Windows phone issues.
Dave Brotheridge: looked through this, and have tried the options in there
Dave Brotheridge: I just need to know where I can manage digital certificates on the phone
Elka: If that site does not work, please contact your phone manufacturer then. Being the primary support for your phone, they are the ones that can best help you and advise you.
Dave Brotheridge: it's a software issue tho
Dave Brotheridge: your software
Elka: Dave, that is the agreement between Microsoft and phone manufacturers.
Elka: Same with computers, if Windows came pre installed, primary support is the computer manufacturer.
Elka: I do hope this would be resolved soon for you.
Elka: Please, should you have additional questions or inquiries, feel free to come back again.
Elka: We are available 7 days a week, 24 hours a day.
Elka: Thank you for contacting Microsoft Customer Service Chat.
Elka: Hope you have a good one.
Chat session has been terminated by the agent."
I dunno, but is it ok for me to be a bit annoyed with that? I didnt even get a chance to respond after my last comment, I think it was a copy/paste terminate job from Elka...
I will call HTC and see if they can help
