There is a way to install and activate the most recent BETA firmware without registering the device’s UDID as a developer.
What you’ll need:
- iTunes 8.2
- iPhoneOS 3.0 BETA firmware file
- iUtilities or DiskAid
- QuickPwn for the specific firmware version
- maybe the carrier-specific features file
Steps
- Install iTunes 8.2
- Maybe make a backup of your iPhone
- Hold Shift and click the Restore button (MAC users: try holding ⌥ while clicking)
- Select the iPhone OS 3.0 firmware file
- Wait until the firmware is installed (~15min)
- Your iPhone will need activation after bootup, but since your UDID isn’t registered at Apple, iTunes will deny the activation
- the trick is to make iTunes think, there’s a 2.2.1 firmware on your phone which it will activate without any problems
- Jailbreak the phone using QuickPwn (make sure, the *Activate** option is unchecked!!)
- now use iUtilities or DiskAid:
-
iUtilities: Click the String Editor tab and find the section System Version
- enter 2.2.1 into the first box and 5H11 into the second one
- click Go
-
DiskAid: Open DiskAid, set the starting node to Root in the bottom left
- navigate to
/System/Libraries/Core Servicesand find the fileSystemVersion.plist - open this file (or copy to PC and open there) with an editor (e.g. notepad.exe)
- change the ProductBuildVersion to 5H11 and change the ProductVersion to 2.2.1. Make sure that ReleaseType is Public
- save the file (or drag from PC back into DiskAid)
- navigate to
-
iUtilities: Click the String Editor tab and find the section System Version
- reboot your iPhone (hold Home and Power until the slider appears)
- launch iTunes and it will activate your iPhone
- now you might revert the changes made by iUtilities or DiskAid, see the table below:

SystemVersion.plist
In case you didn’t make a backup copy, the file looks like this:
<?xml version="1.0" encoding="UTF-8"?>
