Judging by a statement released by Microsoft, it appears they aren’t completely against the unlocking of Windows Phone 7 devices, though they certainly don’t officially condone it. This is a far-cry from Apple’s stance, which seems to be a constant cat-and-mouse game against hackers.
We anticipated that people would attempt to unlock the phones and explore the underlying operating system. We encourage people to use their Windows Phone as supplied by the manufacturer to ensure the best possible user experience. Attempting to unlock a device could void the warranty, disable phone functionality, interrupt access to Windows Phone 7 services or render the phone permanently unusable.
In short, “You break it, you buy it. But don’t let us stop you from picking it up.”
Microsoft has become much more open with the hacking of their products recently, namely Kinect. If the WP7 unlocking community becomes anything like Apple’s jailbreaking community, then it will be interesting to see how it evolves in a environment free of persecution. For the record (and contrast), Palm fully supports the WebOS homebrew community, and it is doing quite well. Then again, the WebOS platform is fledgling, so they may need all the help they can get.
