Unlock iPhone 4 and iPhone 3GS Using Ultrasn0w 1.2.1 [Step-By-Step Guide]

Then iPhone Dev Team already released the latest version of Ultrasn0w iPhone carrier unlock tool with iOS 4.3.1 support to unlock jailbroken iPhone 4 and iPhone 3GS with old baseband version.
Here’s the official announcement of the iPhone Dev Team regarding their new software:

We’ve pushed out the 4.3.1 compatibility fix for ultrasn0w in Cydia — it’s now at version 1.2.1. If you’re not already at 4.3.1 and you need the unlock, please be sure you understand how to get to 4.3.1 using a custom IPSW that doesn’t update your baseband.

This isn’t a new unlock! It’s to allow those who are already unlocked to use FW 4.3.1. It also fixes the signal bar issue for those who aren’t using the unlock but retain an older baseband intentionally.

AFTER INSTALLING ULTRASN0W 1.2.1, PLEASE REBOOT YOUR iPHONE using the normal “slide to power off” swipe. T-Mobile users in the USA also should disable 3G mode in Settings->General->Network.

ONLY Supported basebands: (01.59.00 / 04.26.08 / 05.11.07 / 05.12.01 / 05.13.04 / 06.15.00.

As quoted above, Ultrasn0w 1.2.1 is not a new unlock and it will not unlock new baseband, but it does allow you to maintain your carrier unlock while upgrading to jailbroken iOS 4.3.1 using PwnageTool 4.3 for Mac Os X or Sn0wbreeze 2.5.1 for Windows to preserve the unlockable baseband of the device.

The new UltraSn0w 1.2.1 has capability to unlock iPhone 4 and iPhone 3GS on baseband 01.59.00, 04.26.08, 05.11.07, 05.12.01, 05.13.04, and 06.15.00. iPhone 3GS user need to update the baseband of their device to iPad’s 6.15.00 in order to unlock. So any baseband that is not listed here is not unlockable. You can check the baseband version of your iPhone 4 or iPhone 3GS Settings -> General -> About.

Unlock iPhone 4 iOS 4.0.1 & 4.0.2

There have already been two updates with Apple’s iOS – iOS 4.0.1 released last July, and iOS 4.0.2 released this August. With these two updates and with the fantastic features of the iPhone 4, is it still necessary for you to jailbreak or unlock your iPhones?

Before the advent of jailbreaking, people who buy iDevices accept that their device’s fate will be dictated by Apple as to apps that will be installed, which of the hardware functions can be exploited to their full potential, and which carrier can be used with your iPhone.

Jailbreaking Defined

People who are not open to the “exclusivity” idea found ways to free their phones. That’s when Jailbreaking came to be. Jailbreaking is a process that enables a device to run code, meaning programs or system modification that hasn't been sanctioned by Apple. A jailbroken iPhone for example, will allow its user to download many extensions and themes previously unavailable through the App Store via unofficial installers such as Cydia.

Jailbreaking became so popular that the Copyright Office legalized it last July allowing all iPhone users to gain full and better control of their phones, reiterating that: “When one jailbreaks a smartphone in order to make the operating system on that phone interoperable with an independently created application that has not been approved by the maker of the smartphone or the maker of its operating system, the modifications that are made purely for the purpose of such interoperability are fair uses.”

Features of iOS 4.0.1 and 4.0.2

The iOS 4.0.1 software update didn’t offer new features. Its main purpose was to address the flaw on the number of bars displayed by the iPhone 4 as a consequence of the “deathgrip” problem.
Apple said that an incorrect formula was used and this resulted to an incorrect display of the iPhone’s true signal strength. Due to this flaw, users in low reception areas see more 4 or 5 signal bars when it should be less.

The iOS 4.0.2, on the other hand, was also released to address a security problem found on iOS 4.0 and 4.0.1 created by JailbreakMe, a web-based jailbreaking tool for iDevices that is downloaded into the iOS device through a PDF file. JailbreakMe attacks a hole in the iOS making your iDevices vulnerable to hacking and malware installation.

The iOS 4.0.2 software update has now addressed and patched this vulnerability issue and has provided improvements to Multitasking and fast app switching. It also brought over 100 new features to the iPhone like folders, better mail, iBooks, Home screen wallpaper, and wireless keyboard support among others.

The iOS 4.0.2 works with iPhone 4, iPhone 3GS, and iPhone 3G although not all features are said to be compatible with all devices. Apple said multitasking is available only with iPhone 4 and iPhone 3GS.

Reasons for Jailbreaking and Unlocking

Now, going back to the question of whether or not it is still necessary to jailbreak or unlock your iPhones, many believed this is still a necessity.

Apple mentioned that the iPhone 3GS and 3G are not capable of handling the full features of iOS 4.0.2. Many jailbreakers believe this is not the case. iPhone users of these two models who have jailbroken their phones saw that their units responded quite well to multitasking and to running several apps.

Access to applications is also another reason for jailbreaking because there are far more apps available in Cydia for jailbreakers than through iTunes.

It is also necessary to unlock the iPhone so people who want to be free from AT&T can switch to other carriers like T-Mobile.

Jailbreaking and Unlocking Tools

There are several tools that have already been released for unlocking iDevices. But before you use any of these jailbreaking and unlocking tools, please note that if you need to jailbreak or unlock your iPhone, don’t upgrade it to version 4.0.2 because once your iPhone is upgraded and patched, JailbreakMe will no longer work for your phone.

* JailbreakMe

This is a web-based jailbreaking tool that was tagged as the simplest jailbreaking tool ever that works for all iDevices. JailbreakMe is browser-based and requires no downloads. It could jailbreak iPhone 4 iOS 4 and 4.0.1, including the original iPhone and older iPhone models 3G and 3GS. The tool is so flexible that it could also jailbreak iPad and iPod touch.

JailbreakMe can be accessed by going to the Apple’s Safari App. The jailbreaking tool is then downloaded into the iOS device through a PDF file.

* Redsn0w 0.9.5

This jailbreaking tool released by the iPhone dev team is for jailbreaking iPhone 3G & iPod Touch 2G for 4.0 iOS. The same can be used to jailbreak iOS 4.0.1 and 4.0.2.

* Ultrasn0w 1.0-1

This latest unlocking tool version has recently been released by the iPhone dev team. Ultrasn0w 1.0-1 can unlock iPhone units under different basebands namely:

2. iPhone 3G, 3GS with 04.26.08, 05.11.07, 05.12.01 or 05.13.04 baseband

Just a note… Do not forget to backup your iPhone before jailbreaking or unlocking your phones just in case you would need to restore your phones later on. Jailbreaking your iPhone may also void its warranty.
