There are certainly advantages
to rooting your Windows Phone 7 device, but there's a heck of a downside too -- Microsoft can't update your handset
to the latest and greatest build if you've unofficially patched your phone. Good to know, but what if you've already
done the deed? That's why you'll want the application above, a ChevronWP7
-tested, Microsoft-approved program for pulling your phone out of Bizzaro World and setting things right. Find it at our source link, follow the instructions carefully, and don't fret if the official update doesn't immediately appear after you're done -- developer Chris Walsh says availability of the build depends on carrier approval.
