DO NOT USE THIS TOOL IF YOU NEED AN UNLOCK. THIS REQUIRES YOU TO RESTORE TO 3.1.2 PRIOR TO USING, WHICH WILL UPGRADE YOUR BASEBAND!

Instructions:
1. Update or Restore to 3.1.2 in iTunes (BASEBAND WILL BE UPGRADED FOR 3G AND 3GS)
2. Launch blackra1n
3. Press “make it ra1n”
4. Enjoy!

Take heed people.
Warning 3g and 3gs unlockers, do not upgrade to 3.1.2 using iTunes if you want to keep your unlock. Baseband cannot be downgraded. Check out the dev team’s offerings. Also blackra1n doesn’t hacktivate.

TO FIX ISSUES WITH IPHONE BROWSER, DISK AID, AND OTHER USB BROWSING SOFTWARE:

blackra1n doesn’t patch the services.plist. You will have to do it manually to get usb browsing back.

SSH into your phone and navigate to /System/Library/Lockdown/Services.plist

Copy Services.plist (copy the original for backup) to your computer and open it in a plist editor or a text editor.

Add the following info:

Paste the following key/dict combo above the line that reads
com.apple.crashreportcopy

<key>com.apple.afc2</key>
<dict>
<key>Label</key>
<string>com.apple.afc2</string>
<key>ProgramArguments</key>
<array>
<string>/usr/libexec/afcd</string>
<string>--lockdown</string>
<string>-d</string>
<string>/</string>
</array>
</dict>

If you are lazy, here is a pre-patched services.plist

I recommend editing your own services.plist tho. Reboot your phone and you should be able to use whatever USB browser you want.

Enjoy!

HOW TO JAILBREAK iPhone 3G 3.1

It’s actually really easy but finding the right firmware is always the issue. You will run into about 5 firmware’s available to you by searching torrents.

This is HOW TO JAILBREAK iPhone 3G 3.1 on windows! (XP,VISTA,7)

**WARNING**WARNING**WARNING**

Unless you aren’t worried about potentially upgrading your baseband, I would advise you not to try this tutorial until there is an Unlock method available for the 3.1 Firmware. If you will never need your iphone unlocked then it is perfectly fine to use this jailbreak method.

1. a copy of itunes 8.2 if you don’t already have it installed. download it here Itunes 8.2 Link
2. a copy of custom firmware 3.1 iPhone1,2_3.1_7C144_Custom_Restore_WO_ACT.ipsw (Rogers Canadian Customers) Search, “iPhone 3G 3.1 Jailbroken firmware” at any torrent site.
3. a copy of Redsnow 0.8 (download it here Redsnow 0.8 Link
4. a copy of the OFFICIAL 3.0 firmware

*If you currently have your iphone jailbroken at the 3.0 level, put your phone in RECOVERY Mode (not DFU) and use steps 1,2,3,14 & 15

**If you currently have your iphone at an OFFICIAL 3.1 level, complete all of the steps.

Step 02: Install Itunes 8.2

Step 03: Run Itunes 8.2

Step 04: if you get an “itunes library.itl” error then delete or move it from your itunes folder in “my music”

Step 05: Once you have iTunes 8.2 running, put your phone into DFU mode

Step 06: click “ok” when itunes tells you it detects your phone in recovery mode

Step 07: once your phone is in DFU mode, hold your shift key and click restore in itunes

Step 08: a window will open and you will now locate the official 3.0 firmware file and select it

Step 10: at the end of this process you will likely get a error 1015 or something like that. ignore the error by clicking ok and your iphone should be showing the usb and itunes logo at this point.

Step 11: Now open up Redsnow 0.8

Step 13: At this point your phone might have the USB and Itunes image back on it. This is fine. Open iTunes back up and you will probably be greeted with the “itunes detects your phone in recovery mode”. Click OK.
DO NOT PUT THE IPHONE IN “DFU” MODE AT THIS POINT. Leave it in “Recovery Mode”. Leave it as it is.

Step 15: THAT’S IT! Let it load the 3.1 custom firmware and you are set!

I have done this on 3 3G iPhones and can confirm that this process absolutely works. I hope this helps all of you that have been waiting on a windows version of redsnow that jailbreaks 3.1. This process may take more time but it will work.

Just to clarify a few steps in this process…

If you are on official 3.1 firmware, you have to downgrade to a jailbroken 3.0 firmware and have iTunes 8.2 installed in order to restore the CUSTOM 3.1 firmware. If you are already on a 3.0 jailbroken firmware then just make sure you have iTunes 8.2 installed because itunes 9 will give you error 16xx messages when you do a restore for CUSTOM 3.1 firmware.

I noticed that the majority of my steps look as though this is just to jailbreak to 3.0 SO i just wanted to make it clear that this is actually instructions to jailbreak 3.1
