Merely two days ago, Apple released iOS 5 beta 5 for iPhone, iPad and iPod touch. Basically, Apple releases beta firmware for developers only, who are required to register the UDID of their devices before they can run iOS 5 beta. Many non-developers get their hands on beta firmware when its uploaded to file sharing websites, but they don't have the UDID of their iDevices registered with a Developers Account. What do they do? They follow this tutorial to install iOS 5 beta 5 without Developers Account.
A Developer Account with Apple costs $99 per year and if you are not a developer, its highly unlikely that you will pay that price if you just want to play around with iOS 5 beta firmware for a bit. If you don't know what your UDID is and how you can locate it, follow this tutorial. Without a UDID registration, if you install iOS 5 beta firmware you will be shown the following error: this device is not registered as part of the iphone developer program.
A sincere word of advice for those who throng the internet for developers who offer UDID activations in exchange for a price. They mostly are scams as they usually take people's many and then never contact them back. Also, Apple has been taking down developers that are selling UDID activations. Read the full report on that, here. However, if you are bent on getting the UDID of your device activated, you may try your luck with us as we have been offering free device UDID activation for iOS 5 beta testing. It's completely free and won't get slammed down by Apple. You may fill out the form and see if you get an activation!
Regardless of that, use this simple tutorial documented below in order to install and activate iOS 5 beta 5 on your iPhone, iPad and iPod touch without requiring a developers account.
Install iOS 5 Beta 5 Without Developers Account On iPhone, iPad and iPod touch
Step 1: Download iOS 5 beta 5 for your iDevice.
Step 2: Download iTunes 10.5 beta 5 for Windows and Mac. You need the latest pre-release beta of iTunes so that it sync with iOS 5 beta 5.
Step 3: Install iOS 5 beta 5 on your device using your computer. Don't actually set up your device on iOS 5 beta as first you need to jailbreak it. Follow this tutorial to jailbreak iOS 5 beta 5 tethered and after that, boot your device tethered.. Keep in mind that this does not work with the iPad 2.
Step 4: Basically, you need to delete a key and string from within the filesystem of your device in order to install iOS 5 beta 5 without developers account. To gain access to the filesystem, you need software. i-Funbox for Windows and iPhone Explorer for Mac are the two most perfect software for this job.
Step 5: Launch the relevant software and go to this path: filesystem/library/coreservices/systemversion.plist. Once you locate the systemversion.plist file, right click on it and then open it in notepad. Once opened, locate and remove: <key>ReleaseType</key> <string>beta</string>. When you remove it, save changes to the file.
Step 6: Once you have done this process, reboot your device. Because it is jailbroken, you will have to boot it tethered. Voila! Your device is now running iOS 5 beta 5 without developers account or a UDID activation. No more this device is not registered as part of the iphone developer program errors! If you did this on an iPhone, you shall be able to use cellular services as well.
We strongly caution you not to upgrade your software unlocked iPhone to iOS 5 beta firmware as you will lose your unlock. Factory unlocked or officially unlocked iPhones can be updated to iOS 5 beta 5 using this procedure without any risks.
