Microsoft has finally started to roll-out its first major Windows Phone 7 update a couple of hours ago but it might take over a week (or two) for the refresh to reach you if you have a carrier branded device.
Chris Walsh, member of the ChevronWP7 team has posted a workaround on its blog letting carrier-branded HTC users emulate a non-branded Windows Phone 7 in order to apply the update immediately. The procedure “un-brands” the HTC device and tricks the system into believing it is carrier independent and good to go for the update. Please note that the hack is for HTC devices only and is an advanced technique. Check out the source link if you want to apply’ be warned though, you’re doing it at your own risk!
