Okay, so the WP7 hacking community may not be quite as active as that working tirelessly to keep every facet of Android devices splayed to the breeze, but that's not to say there isn't a skilled group of tinkerers doing their best on Microsoft's best. ChevronWP7 is a clear example of that, and though it's been officially pulled it is still quite certainly being used. Now its functionality has been extended with a second hack that enables you to use Zune to sync your HTC handset without it getting all locked up tight again. You can find all the details on the other end of the source link below, but we'll go ahead and warn you that as soon as the next WP7 version drops this particular unlock will be disabled. Then it'll be on to the next one.
