Recently you may have seen some articles, related to downloading iOS with or without UDID activation. Now, some of you may be wondering what a UDID is. This should help to explain things a little for you. The UDID is a Unique Device Identifier and it’s a sequence that consists of 40 letters and numbers. It’s specific to each device, similar to a serial number but a lot less likely to be guessed.

The reason you have one of these is that, strictly speaking, your Apple device is only supposed to have Apple approved apps and programs downloaded into it. In the case of downloading the new iOS Betas, your UDID must be registered on the Apple Developer Program. Once it is, it will be activated so that you can go ahead and download.
To get your number onto the Developer list you can do one of 2 things:
- Register with the Apple Developer Program for $99 per year and get your UDID added to the list;
- Buy one; you will find a few places on the internet that will sell you UDID developer registration for anywhere between $5 and $10
If you need, or want, to find the UDID on your device here’s how to do it:
- Connect your device to your PC and launch iTunes if it doesn’t open automatically
- Select your device form the list that will appear in iTunes
- Click on Summary
- Click on Serial Number and switch it to display the UDID – serials and UDID’s are not the same number
If you want to keep your number noted somewhere, either write it down in a safe place or, using your mouse or touch pad, copy it and then paste it where you want it stored.
