From http://pocketnow.com/windows-phone/windows-phone-7-cloud-security-cracked-but-theres-a-catch

A Windows Phone 7 security measure designed to perform real-time server authentication has indeed been bypassed, according to a person familiar with the situation, allowing cloud services like Xbox Live, Zune, and Marketplace to function on ported copies of the operating system, such as on an HTC HD2. However, since the method requires extracting what's known as a unique private key (PVK) from the device provisioning partition (DPP) of an actual WP7 handset, it is far from ready for widespread deployment.

Specifically, Microsoft has apparently employed a variation of Windows Genuine Advantage on the new platform, so we're told that its servers will only authorize three activations associated with a given PVK (four if you count the factory provisioning). Not only will further activation attempts fail to give those handsets cloud service access, but the initial devices using the now-blacklisted key actually lose their networked privileges as well -- including what was presumably the retail WP7 unit.

Several different methods are being attempted to bypass the limitation, including the search for a so-called "corporate key," which would essentially be a universal PVK for large-scale activations. Unfortunately, because all devices are security-flashed at the factory, such a key may not even exist. Secondly, overseas developers -- beyond the reach of Microsoft legal, apparently -- are said to be hacking the different bits of the device-side authentication piecemeal, but because of the unusually intricate security measures employed by Redmond, "it doesn't really look good" according to our source.

At this point the most we can say is that Windows Phone 7 will almost definitely be coming to HD2 and possibly a few other well-spec'ed devices, but the capabilities of any services that "phone home" will probably be limited -- if not because of the technical hurdles, then due to the fact that any use of cracked keys could be considered an attack on Microsoft's servers; in other words, this seems to move beyond the "don't ask, don't tell" status quo with regards to Windows Mobile ROM flashing into territory that the company might consider actionable. So unless you're handy with JTAG dumping methods and have a good friend willing to share their PVK, you're probably better off just going out and buying a Windows Phone than waiting around for what might be forever to get full functionality on your legacy handset.

Why dont Microsoft get it? Their ignorance is sending themselves into oblivion. Can you imagine google putting keys on their OS so you can only have so many copies, and banning you if you use more? Its 180 degrees in the wrong direction. Its like they dont want people to use their OS?!
Look what happened with Kinect! Their lawyers swooped on a group offering a reward for an open source SDK to kinect and MS threatened legal action to anyone using for non x360 purposes before the penny dropped that they would sell a sizable proportion of them to the dev community! Ive got one, and I wouldnt have bought one and they wouldnt have £130 of my money if the SDK they didnt even have to write existed. Total fuckwits.

+1 Microsoft is working against its self here. I am running the ported version of android on my hd2 and i have bought a few apps through their marketplace. It doesnt make sense for a company to make it difficult for people to purchase items through their market

I am pretty sure MS really does not care about recieving 30% of a 1.99 or .99 for an app in exchange for people "stealing" the cost of their OS to the OEMs.

But, its only a matter of time before some kind of WP7 HD2 port comes. MS must realize that its inevitable, it will happen sooner or later. They may as well then get the money from the marketplace. The guys above are right, MS are totally shooting themselves in the foot.

no sd launch? How is this rom expected to be launched? sd card or RAM? or worse nand :confused:
I would prefer ram because that build would be faster than SD. I wouldn't want it to be nand because I just flashed gingerbread onto my HD2. I don't wanna have to choose which to use since I like them both.
