Unlock LG Optimus 7 Permanently Without ChevronWP7 [How To]

Windows Phone 7 is pretty uptight when it comes to getting full access over your device. Developers are always looking for ways to jailbreak their WP7 device and Windows always comes up with a new method to relock it. The most common method used for jailbreak is to apply ChevronWP7 to your phone. But it has been observed that even a Chevron unlocked phone will relock as soon as a new operation system update becomes available. This renders the whole jailbreaking process pretty pointless. However for LG Optimus 7 users there is now finally a workaround for this issue which keeps your device developer unlocked for as long as you want.

The method has been proposed by XDA forum’s senior member airwa1kin7 and is based wholly on modifying registry values. Tinkering with your WP7 registry is always dangerous so beware of what you are doing.
