Previous day Apple released iOS 5 beta 6 for iPhone, iPad and iPod. We also mentioned in our post that this feature is only for those who are registered developers and have UDID registered iPhone, iPad and iPod touch. If you don’t have a Developer Account which costs $99 per year it can’t be installed because  iOS beta firmware is only intended for developers.

So don’t be upset if you don’t have UDID registered iPhone, iPad and iPod touch because we are going to teach you the procedure to install iOS 5 beta 6 without UDID registration or even a Developers Account, So just follow these steps to install and activate the IOS 5 beta 6 on the iPhone, iPad and iPod without a developer account.

These Are To Install iOS 5 Beta 6 Without UDID Registration Or Developers Account:

Step 1: 

Download the following:

Download iOS 5 beta 6 ipsw for iPhone, iPad and iPod touch
Download iTunes 10.5 beta 6 for Windows and Mac
Download i-Funbox for Windows or iPhone Explorer for Mac

Step 2:

 Once you have downloaded iOS 5 beta 6 ipsw for your device on the computer, follow this guide to install iOS 5 beta 6 on iPhone, iPad and iPod touch. When installation completes, don’t do the PC-free iOS 5 setup. You first need to jailbreak your device.

Step 3: 

Follow the tutorial to jailbreak iOS 5 beta 6 tethered using redsn0w, on Windows and Mac. This won’t work on the iPad 2. Jailbreak is necessary because we need access to the root filesystem of the device.

Step 4: 

After the jailbreak has been done, we now have to delete a certain key and string from within the filesystem to install iOS 5 beta 6 without UDID registration. To do this, you may download i-Funbox or iPhone Explorer, depending upon what computer you use.

Step 5: 

After you have downloaded and installed the relevant software for your Windows or Mac computer, connect your device to the computer and launch the software. Using the software, navigate to this path: filesystem/library/coreservices/systemversion.plist. After locating this .plist file save it to your desktop.

Step 6:

 Once saved to the desktop, right click and open this .plist file in either Notepad or Text Editor. Now locate this: <key>ReleaseType</key> <string>beta</string> and remove it. Save changes to the file.

Step 7:

 Copy this file back to its original location in the filesystem of your device running iOS 5 beta 6. Close the software and reboot your device.
