[Windows Phone 7 Development and Hacking] Heathcliff74:
Luckily I had some Wireshark logs laying around :) I extracted these URL's. I think you got it all when you download these. You need them all, except the last two are optional. If you have an Omnia 7 I suggest you download the driver package too. If you are Dutch you can download the Dutch language pack too.
