Hai, Jailbreak is different from unlock. Jailbreak is allow you to download the third party applications. You can jailbreak your iPhone using free software which is available online. And unlocking will remove your network lock.. You can remove this lock by using Mobileunlocksolutions.com .They will help you to unlock your iPhone remotely.
