How to make custom iOS 6.1.3 IPSW to preserve iPhone 4/3GS BB for unlock:
Part 1: In this part you have to build and instal custom iOS 6.1.3 firmware and if you are not using official SIM card then you will need ‘Hacktivation’.
Step 1 : First of all download original iOS 6.1.3 firmware (IPSW) for iPhone 4 or iPhone 3GS from here.
Step 2: Install and run sn0wbreeze.
Step 3: Click browse and locate the original iOS 6.1.3 that you just downloaded.
Step 4: Sn0wbreeze will identify the IPSW file. Click Next and select Expert Mode.
Step 5: Now it will ask you whether you want to hacktivate or not. Select “Yes”. Now wait until sn0wbreeze completes building the custom iOS 6.1.3 for you.
Once the custom iOS 6.1.3 is ready you will find it on your desktop. Before restoring your iPhone, you MUST put your iPhone into pwned DFU mode using iREB. This allows it to accept custom firmware. Otherwise, you’ll get an error message during restore. iREB will appear as soon as custom firmware is built. You can also access it on the menu bar of sn0wbreeze.
To begin restoring, be sure your iPhone is already in pwned DFU mode (black screen) then launch iTunes, press shift on your keyboard and click restore. Select the custom firmware that was just created. To be sure, the file name always begin with sn0wbreeze_iPhone_xxxxxxx.
Step 1: Launch Cydia and add the following repo by going to Manage > Sources > Edit > Add:
Step 2: Search for ultrasn0w 1.2.8.
Step 3: Install ultrasn0w 1.2.8.
Step 4: Reboot your device. Remember to use iBooty to boot your iPhone as the jailbreak for A4-based and newer 3GS devices are still tethered!
(B) Unlock with Gevey SIM [for iPhone 4 baseband 02.10.01, 03.10.01 or 04.10.01 only]
Step 1: Eject your SIM tray and reboot your iPhone.
Step 2: Once restarted, unlock your screen. Turn off 3G and cell data (you can turn these on later). Insert your SIM tray along with your SIM card and Gevey SIM.
Step 3: Wait for Accept Screen. Tap Accept.
Ste 4: You will see No Service (in iOS 4.x, you will see one signal bar). Wait for 15-20 seconds and dial 112. Hang up after 1-2 seconds.
Step 6: Now turn on Airplane Mode and wait for ‘NO SIM CARD INSTALLED’ message. Turn off Airplane Mode and you will see ‘SIM FAILURE’ and tap OK. Your iPhone will show network signals.
