iphone 4 unlock guide !!!!

Ultrasn0w 1.2.3 has been released today to make the unlock compatible with iOS 4.3.3 on iPhone 4 and 3GS, running on the old baseband.

It should be noted though that this release of Ultrasn0w is not a new unlock for iPhones with newer basebands, instead, it only fixes the compatibility issues on the existing devices, which are jailbroken (with preserved basebands: 01.59.00 / 04.26.08 / 05.11.07 / 05.12.01 / 05.13.04 / 06.15.00) on iOS 4.3.3.

For iPhone 3GS Only: How to Update iPhone 3GS to 06.15.00 Baseband for Unlock:
Ultrasn0w 1.2.x unlocking requires that your iPhone 3GS is jailbroken with 06.15.00 baseband.

Note: Updating iPhone 3GS baseband to iPad’s 06.15.00 might result in loss of GPS functionality.

Step 1: First up, you will have to jailbreak your iPhone 4 or 3GS on iOS 4.3.3 and preserve the old baseband using either PwnageTool on Mac, or Sn0wbreeze on Windows. Instructions on how to jailbreak iOS 4.3.3 using PwnageTool can be found here, and for Sn0wbreeze can be found here.

Step 2: Once you are done with the jailbreak, you can now unlock your iPhone on the supported basebands using Ultrasn0w 1.2.3 from Cydia. To do this:

  • Start “Cydia” on your iPhone.
  • Touch on “Manage” tab on the bottom.
  • Now touch on “Sources” as seen in the screenshot below:

Untethered jailbreak for 4.3.3

The iPhone Dev Team has released updated version of both Redsn0w and Pwnage tool to jailbreak iOS 4.3.3 untethered using i0n1c’s untethered exploit.

UPDATE: jailbreak for Verizon iPhone 4 running iOS 4.2.8 is also available.

 three in a row!  Apple released iOS 4.3.3 on Wednesday, and once again the untethered jailbreak exploit that @i0n1c created for 4.3.1 still works.  That makes it an unprecedented three firmwares where the same userland exploit works.  We’re not exactly sure why Apple hasn’t fixed the hole yet, but we’re not complaining!

Today’s PwnageTool and redsn0w incorporate @i0n1c’s port to 4.3.3 (it’s ironic that such a long-lasting untether doesn’t even have an official name!).  It also of course uses geohot’s limera1n bootrom exploit to inject the jailbreak. The 4.3.3 untether works on all devices that actually support 4.3.3 except for the iPad2:

  • iPhone3GS
  • iPhone4 (GSM)
  • iPod touch 3G
  • iPod touch 4G
  • iPad1
  • AppleTV2G (v4.3 8F202)

NOTE: Those of you who rely on a carrier unlock MUST STAY AWAY from Redsn0w and stock iOS 4.3.3 firmware. Instead use PwnageTool for Mac, or Sn0wbreeze for Windows.

Step 1: Download iOS 4.3.3 for your version of iOS device.

Step 2: Update/Restore to iOS 4.3.3 firmware using the IPSW file you just downloaded via iTunes 10.2.2.

Step 3: Start Redsn0w and point it to the official iOS 4.3.3 firmware file.

Step 4: Now select “Install Cydia” and click “Next”. Optionally (if available), you can also select any other option you like.

Step 5: Now make sure your device is both OFF and PLUGGED IN to the computer before you click “Next”.

At this stage you will be presented with a screen where you will be guided on how to enter DFU mode. Quickly hold “Power” button and then while holding the “Power” button, you will now have to hold “Home” button too. Now after few seconds release “Power” button but keep holding “Home” button until installation begins.

Step 6: Sit back and enjoy while Redsn0w does the rest for you. Once done, your iPhone, iPad or iPod touch will restart automatically and you will find it fully jailbroken (untethered) on the latest iOS 4.3.3 firmware.
