Unlock iPhone On 5.0.1 iOS

We have been getting a lot of comments by people on the full 5.0.1 untethered jailbreak guide regarding the unlock procedure. In this post, we will tell you how exactly you can unlock iPhone on 5.0.1 iOS after you have jailbroken it untethered.

How To Unlock iPhone On 5.0.1 iOS Using Ultrasn0w 1.2.5:

First and foremost, you need a jailbroken iPhone. Always keep in mind that your software unlocked iPhone should have an unlockable baseband preserved. If the baseband has been upgraded to higher ones not supported by ultrasn0w, then your iPhone 4 or iPhone 3GS is nothing more than an expensive paper brick.

Which Basebands Are Supported By Ultrasn0w iPhone Unlock?:

In order to unlock iPhone on 5.0.1 iOS using ultrasn0w, your iPhone 3GS should have any one of the following baseband: 04.26.08, 05.11.07, 05.12.01, 05.13.04 or 06.15.00. Ultrasn0w can only unlock baseband 01.59.00 on iPhone 4. If you upgraded to iOS 5.0.1 firmware without preserving your baseband, get a stack of papers ready to hold together with your iPhone.

It is imperative to keep in mind that if your iPhone 4 or iPhone 3GS relies on a software based unlock, you must never upgrade to a newer version of iOS firmware until and unless a tool is released to preserve unlockable baseband while upgrading firmware. Follow this guide to learn how to preserve baseband while updating iOS firmware on your iPhone. You're now ready to unlock iPhone on 5.0.1 iOS if your iPhone is jailbroken untethered on this firmware and has its unlockable baseband preserved.

Step 1: Launch Cydia. Tap on Manage, followed by Sources. Tap on Edit then on Add.

Step 2: Add the following repository: repo666.ultrasn0w.com
