BlackSnOw Jailbreak Tool For iOS 4.0 released
When we covered the release of the iOS 4 unlock for iPhone 3GS using Blacksn0w, it was clear that many owners of iPhone 3GS would like to unlock iOS 4 on their smartphones. So now, we present a step by step guide to unlock iOS 4 on your iPhone 3G/GS using Balcksn0w RC2.
Before starting, a few important things to know about the Blacksn0w RC2 unlock tool are:
- This tool ONLY works on modem firmware version 05.11.07. Do not use the tool to unlock your iOS 4 if your baseband version is different than 05.11.07. It WILL NOT work.
- V1.2: Support for iOS 4.0 GM. Backwards compatible to 3.1.2/3 as well. V1.1: MyWi tethering fix Geohot’s unlock for 3.1.2/3.1.3/4.0GM on the iPhone 3GS (and probably 3G)
- With 3.1.3 & 4.0 GM patch by msft.guy. Packaged by Pushfix.info
- This is an unofficial release but Geohot has given the permission to redistribute blacksn0w. All known issues with Wi-Fi loss and boot loops seem to be fixed. If it doesn’t work for some reason, you should still get the SpringBoard. This allows you to uninstall if necessary. It is a little slower to boot because of the increased safety of the release. A 3GS boots to cell connection established in about 90 seconds in iOS 4 now (50% slower than 3.1.X).
Reminder: The step by step guide which follows is to unlock your iPhone 3GS on iOS 4, 05.11.07 baseband using blacksn0w RC2. Also Blacksn0w binaries are a little buggy, and this will result in your phone taking at least 90 seconds on every reboot to catch carrier signals. Again, DO NOT follow this guide if your baseband version is different than 05.11.07. Okay, here we go with the guide:
Step 1: First, you need to jailbreak your iPhone 3GS using PwnageTool. The step by step guide for doing this is available here.
Step 2: After you’re done jail breaking your iPhone from step one, grab hold of Blacksn0w RC2 from Cydia. To do this, start “Cydia” on your iPhone then go to “Manage” tab at the bottom, and click on “Sources” as shown in the screenshot below:
Step 3: Click on “Edit” then on “Add” after which you will be promoted to enter a URL source. Type the URL: http://cydia.pushfix.info (without quotes) then click on “Add Source”
Step 4: Cydia will start Installing the new source which you entered, so wait while it does that
Step 5: After Cydia is done installing the source, search for “Blacksn0w RC2 for iOS 4″ (again, without quotes) and install this app. This app, once installed, will automatically unlock your iPhone device. A screenshot may suffice:
Step 6: After the app has installed, just restart your iPhone and wait at least 90 seconds before iPhone picks the signals of your carrier. Enjoy unlocked iOS 4 on your iPhone 3GS.
