Just called microsoft, and got a key EZ Mode
So i just got a WP7 product key with NO problems by simply calling them... here's my story;
Rep: How can i help you?
me: I just purchased an HTC HD7 online and I need a activation key for live services.
Rep: Okay, what you need is a product key?
Rep: okay (long story short, he wanted my first / last name, and email address)
me: (supplied the info)
Rep: Please wait while i generate a key for you.
Rep: Now do you have the HD7 with you?
Me: No, i just purchased it online through T-Mobile online, and they told me, once i get the phone, i can come down to the nearest location and they would help me activate it, or just call microsoft and get an activation key from them, and i live far from the nearest Tmobile store so i figured i'd just call and do it myself.
Rep: okay, that's fine, let me know when you're ready i can supply you with the key
Key recieved, no further questions asked. That simple... call literaly took about 3-4 minutes.
just thought i'd share how easy it was, for all of you curious on obtaining a key.
