Ultrasn0w 1.2.8 Unlock iOS 6.1 for iPhone 4 3GS Old Basebands

Ultrasn0w is probably the perfect tool when it comes to unlocking the iOS 6.1 provided that Evasi0n has already jailbroken the firmware. It is vital to know beforehand that this unlock is not applicable to the latest basebands due to the simple reason that this is merely an update for compatibility with Apple iOS 6.1 Firmware.

If your Apple phone is already unlocked using the Ultrasn01 then there obviously no need to go about re-installing. A reminder here, this fix is only possible with old versions of the iPhone, namely the 3GS and 4 having either 6.0.1 or 6.1

How to Unlock iOS 6.1 while making use of Ultrasn0w 1.2.8

  • Next, run Cydia from the Springboard
  • Moving on, select the manage icon which can be found at the bottom of the device to tap on the resource option.
  • After doing so tap on Edit and press Add. A box will pop up in which you should feed in the following: http://repo666.ultrasn0w.com. After doing so simply select Add source and press ‘Return to Cydia’
  • Next move on to searching for the Ultrasn0w tool and commence the installation process.
  • This step will be purely automatic and one can leave the device unattended for a while and stretch the legs.
  • After the installation process is completed then all that remains to be done is to reboot the device.

Congratulations, your device has been successfully unlocked and can be easily used on a number of carriers.

Other Options for Unlocking the iPhone

If there seem to be some complications with unlocking your phone through this method then there is no need to worry. There is another method available that takes longer and has quite a bit of ‘Ifs’ associated with it but is pretty effective.

First, make sure whether the device is locked to its current carrier. Next, if it’s unlocked then gauge the eligibility of this unlock. If all the previous steps are in order then all that remains is to find out your IMEI number, which can be accessed through this set of menus: Settings > General > About.

If everything goes as planned the company will send instructions detailing how to unlock the device and following these should do the trick. The bonus here is that future updates for firmwares and basebands will be possible without needing to use the Ultrasn0w tool.

There are quite a few other services out there that provide this unlocking in an easy manner but the above method is generally considered to be the safest and guaranteed to work. It can unlock carriers including AT&T, O2, Sprint, Vodafone and Rogers.  To pay a visit to the official unlocking site, simply go to Jailbreakwizz.com.
