Yes, that is right, I am indeed talking about downloading UnlockJB 2.0, the latest version of the Unlock-Jailbreak.net Team tool that brings an untethered jailbreak and unlock to the majority of our iPhone 5S,5C,5,4/4S/3Gs iOS 7.1.2 devices.

We have found ourselves in an all too familiar situation over the last couple of months, stuck in limbo between wanting to update to the latest official firmware, but not knowing when or indeed if a functional jailbreak would be released. Keeping history in mind, we should be able to rest easy in the fact that researchers such as SoftUnlockiPhone have always managed to escape the securities put in place by Apple to bring a jailbreak and unlock iPhone 5S,5C,5,4/4S/3Gs iOS 7.1.2 to the masses, but there will always remain a small part within us that has doubts each time Apple pushes a new version of iOS.Some UnlockJB updates are just minor vanity house updates or meager bug fixes, but it gives me great pleasure to announce that the just-released version 0.9.12b1 uses UnlockJBís exploit to jailbreak iOS 7.1.2 untethered on iPhone 5S,5C,5,4/4S/3Gs and Unlock iPhone. The fruit companyís latest and greatest firmware version hasnít coughed up many bugs hitherto, but the limited jailbreak capabilities have meant that many users still havenít been able to enjoy optimal performance, until now.If you have already jailbroken your device using UnlockJB, you really donít need to use Redsn0w now. But if you are a unlocker, and have been waiting for a tool to do a custom firmware (A4 devices only), you would be glad to know that UnlockJB has finally been updated with support for 7.1.2 untethered and unlock.We are once again sitting right in the middle of that beautiful time period when updated jailbreaking tools are available, which allow us to free our iOS devices from their technical shackles. For those who have been sitting with an iPhone, iPod touch or iPad running Appleís iOS 7.1.2 firmware, you will no doubt be aware that after weeks of hard work and research, UnlockJB and his team have released an untethered jailbreak/unlock for all existing iOS 7.1.2 devices, excluding the third-generation Apple TV.
