To acquire complete control over your Windows Phone 7, you need to have jailbreak it. The process of jailbreaking unlocks your device. An unlocked device means that you have purchased a developer’s license from Microsoft, certifying that you are allowed to have an unlocked device. But in the smartphone world everything has a workaround and there is always that little hack or fix that lets you do anything with your phone in any way you want. We covered unlocking a  WP7 device in our unlocking guide, but if you are a Samsung Focus user and would like to get a more detailed and easy-to-follow walkthrough then here it is!

Unlocking can be a bit risky so be sure you know what you are doing before taking this up.
