Using Sn0wbreeze you can create custom firmware not just for jailbreak but also you can update to iOS 6.1.3 without changing baseband for unlock iPhone 3GS and 4. In this case, the modem firmware remains as it was before on custom 6.1.3 firmware, assembled by sn0wbreeze.
Updated sn0wbreeze 2.9.14 includes apticket validation. Also it was added the support for tethered jailbreak for iOS 6.1.3 devices running A4 processor chip. All other models are not supported and don’t look for it because you won’t find it.
Note: If your iPhone is with old bootrom you can perform untethered jailbreak using Simple Mode which dosen’t change baseband as well.

Step 2: After the program is up and running click “Next” and select the firmware by clicking “Browse”. Choose iOS 6.1.3 IPSW file you downloaded earlier to preserve baseband.
Step 3: The application automatically checks the compliance of the selected firmware and connected device.
Step 4: You will now be prompted to select one of the modes:
  • iFaith Mode
  • Simple Mode
  • Expert Mode
  • Baseband Preservation Mode.

iFaith Mode. You can create the firmware using saved SHSH. If you have SHSH blobs for iOS 6.1.2 you can downgrade 6.1.3 using locally saved blobs or with ifaith or with TinyUmbrella.
Baseband Preservation Mode will be useful only for owners of iPhone. With it, you can build custom firmware without jailbreaking and baseband update.
Simple Mode (recommended for inexperienced users) makes jailbroken custom iOS 6.1.3 firmware without changing baseband. After restore Cydia and afc2 will be installed by default. Owners of locked phones must answer Yes to the question of whether to activate the phone. Also click No if your device is already factory unlocked. Or you can always unlock iPhone using IMEI number and choose the mode you like.
Expert Mode makes jailbroken iOS 6.1.3 custom firmware preserving baseband and allows you to select additional features. You can enable multitasking, wallpaper and display the battery charge percentage for iPhone 3G. Change the size of the root directory, hacktivation, install SSH and animated Bootle. Owners of locked phones must be sure to select “Activate The iPhone”.
Step 5: So choose Expert Mode and click “General”.
Step 6: In the following window you can make some setup. For example: check “Activate The iPhone [Hactivate]” for locked devices.
Step 7: Then click “Build IPSW” and “Next”.
Step 8: Sn0wbreeze will begin the process of creating custom firmware for iOS 6.1.3 update. You will see “Done” once the process is complete.

Step 9: Now you need to put the device in a mode “DFU”.To do this, open iBooty which comes with Sn0wbreeze by default. Select your device and click “Start”. Follow instruction and the program will show the status of iPhone.
Step 10: Clean file Hosts on your computer before we continue:
  1. Open file: Windows XP – C: \ Windows \ System32 \ drivers \ etc \ hosts
  2. Windows 7 – C: \ Windows \ System32 \ drivers \ etc \ hosts (Run Notepad with Administrator privileges by right clicking on the program and Run as Administrator.)
  3. Delete lines containing “gs.apple.com” and “localhost”.
  4. Save.
  5. Close.
Step 11: Then run iTunes if it is not running. Hold down the Shift key on your keyboard and click “Restore” in iTunes and set the path to the firmware, which was built by sn0wbreeze. The firmware will be on the desktop of your computer.
Step 12: After a while, your iPhone will be running custom iOS 6.1.3 without baseband update.
Remember: This is a tethered jailbreak, so do not forget to run iBooty every time after iPhone reboot or discharge.

Unlock iPhone Running Jailbroken with Sn0wbreeze iOS 6.1.3

First  go to Settings -> General -> About and check the modem firmware. Yuo can use Gevey Sim which you used before on supported baseband or Ultrasn0w. If Ultrasn0w then follow steps below.
Supported Baseband
  • IPhone 3GS 04.26.08, 05.11.07, 05.13.01, 05.13.04, 05.12.01, 06.15.00.
  • IPhone 4 01.59.01.
Step 1: Start Cydia.
Step 2: Go to “Search” on the bottom of Cydia iOS 6.1.3 program.
Step 3: Type “Ultrasn0w” and tap “Search”.
Step 4: When iPhone Dev team or new evad3rs team will release Ultrasn0w to support iOS 6.1.3 you can choose it and install. You can try with earlier versions but I don’t think it will help.
Step 5: After installing turn iPhone off and repeat the procedure with iBooty.
Step 6: After rebooting you will have a fully unlocked iPhone 4 / 3GS running jailbroken iOS 6.1.3.
But if you failed or something went wrong, you could always choose IMEI unlocking service and corect the situation. If your iPhone will be factory unlocked you will be able to use the same Sn0wbreeze 2.9.14 for jailbreak, downgrade and many other things and still be forever unlocked.
Here below you can choose from services that will help you to forget about baseband update or preservation:
  • Unlock iPhone locked to AT&T USA Carrier.
  • Unlock iPhone locked to carriers like Rogers, Vodafone, Orange, O2 and many others.
I hope this guide was helpfull for you and you can enjoy your unlocked and jailbroken iPhone running on custom iOS 6.1.3 without baseband update. Use share buttons to provide this info to your friends and other users who need it.
